When looking at a bright incandescent light bulb What kind of a spectrum did you see through your spectrometer?
The spectrum we see emitted from an incandescent bulb consists of colors that blend into one another through a continuous spectrum of red- orange-yellow-green-blue-indigo and violet (ROYGBIV). This continuous spectrum has no colors missing.
Which can be described with wave like behavior quizlet?
A form of energy exhibiting wavelike behavior as it travels through space; can be described by wavelength, frequency, amplitude, and speed.
Which of the lenses has the greater magnification group of answer choices?
The oil immersion objective lens provides the most powerful magnification, with a whopping magnification total of 1000x when combined with a 10x eyepiece.
What type of spectrum does an incandescent light bulb produce and which law tells us that?
An incandescent light bulb produces a continuous spectrum because the source of the light is a metal filament (wire). A continuous spectrum emanates from the dark parts of the universe. The peak of this radiation corresponds to a temperature of about 2.7 degrees Kelvin.
Why do the spectra of other light bulbs appear more like a complete rainbow?
Light from a fluorescent bulb looks slightly different from sunlight because it is made of a different combination of colors. The Sun emits a nearly continuous spectrum (a complete rainbow), while fluorescent bulbs emit some colors of the rainbow and not others.
How is quantum of energy related to an energy change of matter?
How is a quantum of energy related to an energy change of matter? Matter loses or gains energy only in multiples of one quantum. Matter transfers energy in quanta.
Is light a wave or a particle or both explain your answer quizlet?
Visible light is carried by photons, and so are all the other kinds of electromagnetic radiation like X-rays, microwaves and radio waves. In other words, light is a particle. How does light act as a wave? Light behaves as a wave – it undergoes reflection, refraction, and diffraction just like any wave would.
How did the simple addition of a convex lens magnify an object to make it appear larger than it is?
Magnifying glasses make objects appear larger because their convex lenses (convex means curved outward) refract or bend light rays, so that they converge or come together. In essence, magnifying glasses trick your eyes into seeing something differently than it really is.
When an object is placed between the focal point and the convex lens the image produced is?
When object is placed between convex lens and focal point, image formed is virtual and magnified which is shown in the diagram.
Which type of spectrum is rainbow?
the visible light spectrum Rainbows are part of the visible light spectrum. They form when the light wave passes through a prism, like a water droplet, and is refracted – or bent – by the prism.
How is the obtained spectrum from fluorescent light LED light incandescent light candle light and daylight different from one another in terms of intensity?
Fluorescent lights produce a quality of light that limits the colors projected. This can create an unpleasant atmosphere in a space. On the other hand, incandescent light gives a continuous spectrum of light, most closely mimicking daylight or sunlight or the illumination of thousands of candles.
What is the difference between the spectrum produced by the sun and the spectrum from the fluorescent lights?
Light from a fluorescent bulb looks slightly different from sunlight because it is made of a different combination of colors. The Sun emits a nearly continuous spectrum (a complete rainbow), while fluorescent bulbs emit some colors of the rainbow and not others.
What type of spectrum would you see when you look at light from an incandescent bulb that passes through a cloud of cool gas?
When the light source is viewed through a cloud of cool hydrogen gas, a series of dark absorption lines appear, superimposed on the spectrum at wavelengths characteristic of hydrogen. The lines appear because the light at those wavelengths is absorbed by the hydrogen.
What is the impact of de Broglie’s wave-particle duality and the Heisenberg uncertainty principle on the current view of electrons in atoms?
What is the impact of de Broglie's wave-particle duality and the Heisenberg uncertainty principle on the current view of electrons in atoms? Both contributed to the electron cloud theory.
What is the relationship between emitted electromagnetic energy E and frequency that was discovered by studying blackbody radiation?
Conclusion. Electromagnetic radiation can be described by its amplitude (brightness), wavelength, frequency, and period. By the equation E = h ν E=hnu E=hν , we have seen how the frequency of a light wave is proportional to its energy.
Is light a wave or a particle or both explain your answer?
Light Is Unequivocally a Wave! Some 100 years after the time of Newton, French physicist Augustin-Jean Fresnel (1788 to 1827) asserted that light waves have an extremely short wavelength and mathematically proved light interference. In 1815, he devised physical laws for light reflection and refraction, as well.
Why light is both a particle and a wave?
Light can be described both as a wave and as a particle. There are two experiments in particular that have revealed the dual nature of light. When we're thinking of light as being made of of particles, these particles are called “photons”. Photons have no mass, and each one carries a specific amount of energy.
What is the difference between linear magnification and angular magnification or magnifying power our view of an object depends on which of these two?
The two basic types of magnification are: Linear magnification: It refers to the ratio of image length to object length. Angular magnification: It refers to the ratio of the tangents of the angles subtended by an object and its image from a given point.
What part of the microscope further magnifies the image formed by the objective lenses where is this part located?
The eyepiece serves to further magnify the real image projected by the objective. In visual observation, the eyepiece produces a secondarily enlarged virtual image.
What kind of image is formed when an object is placed between the focal point and the vertex?
Such images are called virtual images because they are not formed by the actual convergence of reflected light rays at the image location. Virtual images are always formed on the opposite side of the mirror as the object.
When the object is placed at the focus of a concave lens the image formed is?
When object is at focus of the concave mirror. hence the image is formed at infinity and image is real, inverted and highly magnified.
What is a full circle rainbow called?
The glory of a circular rainbow This is called a glory, which NASA defines as an optical phenomenon that "looks like small, circular rainbows of interlocking colors." This glory was photographed from a plane over South Africa.
Is a rainbow a full circle?
Rainbows are actually full circles. The antisolar point is the center of the circle. Viewers in aircraft can sometimes see these circular rainbows. Viewers on the ground can only see the light reflected by raindrops above the horizon.
How does the color of an object differ when it is illuminated by candle light and by light from a fluorescent lamp?
In short, the colors we perceive change in accordance with the wavelength component of the light source illuminating the objects we see.
How do the spectra of sunlight fluorescent light and incandescent light sources compare?
An incandescent bulb is on what's called a continuous spectrum. This means that all visible colors are present. In contrast to a fluorescent light spectrum, which only produces a limited amount of color, the incandescent light spectrum is more dynamic.
How is sunlight different from light produced by a light bulb or by a fluorescent light bulb?
While natural light is produced by the sun, artificial light sources can include incandescent bulbs, fluorescent tubes and light-emitting diodes (LEDs). Sunlight contains all the colors of the spectrum, which is necessary for photosynthesis in plants.
What type of spectrum is observed in the light from the Sun and other stars?
The full electromagnetic spectrum. The spectrum of the Sun appears as a continuous spectrum and is frequently represented as shown below. This type of spectrum is called an emission spectrum because what you are seeing is the direct radiation emitted by the source.
In what type of spectrum continuous or line will you observe all the colors of the rainbow?
The visible "electromagnetic spectrum" is a continuous spread of all of the spectral colors, arranged according to wavelength (i.e. red, orange, yellow, green, blue, and violet).
What is de Broglie equation explain relation between wavelength and momentum with the help of de Broglie equation?
λ = h m v = h momentum : where 'h' is the Plank's constant. This equation relating the momentum of a particle with its wavelength is de Broglie equation and the wavelength calculated using this relation is de Broglie wavelength.
What are de Broglie waves How does the de Broglie wavelength vary with momentum of moving particle?
of moving particles varies with their linear momentum (p). ii) State any one phenomenon in which the moving particles exhibit wave nature. of moving particles varies with their linear momentum (p). De-broglie wavelength varies inversely proportional with the linear momentum.
