What happens to light when it falls upon a material that has a natural that is a resonant frequency equal to the frequency of the light?
What happens to light when it falls upon a material that has a natural frequency equal to the frequency of the light? it is absorbed. At resonant frequencies at which amplitudes of oscillation are large, light is absorbed.
What accounts for the whiteness of a cloud?
Clouds are white because light from the Sun is white. As light passes through a cloud, it interacts with the water droplets, which are much bigger than the atmospheric particles that exist in the sky.
What color results when red is subtracted from white light quizlet?
Infrared light is most absorbed by water. What part of the visible electromagnetic spectrum is most absorbed by water? What color results when red is subtracted from white light? When red is subtracted, the result is cyan.
What accounts for the whiteness of a cloud quizlet?
What accounts for the whiteness of a cloud? Water droplets of different sizes scatter a variety of light frequencies, resulting in a white cloud.
What is the effect on the color of a cloud when it contains an abundance of large droplets quizlet?
Water droplets of different sizes scatter a variety of light frequencies, resulting in a white cloud. What is the effect on the color of a cloud when it contains an abundance of large droplets? The cloud becomes dark.
What happens to light of a certain frequency when it is incident upon a material whose natural frequency is the same as the frequency of the light?
If a light wave of a given frequency strikes a material with electrons having the same vibrational frequencies, then those electrons will absorb the energy of the light wave and transform it into vibrational motion.
What causes clouds to be different colors?
The color of a cloud depends primarily upon the color of the light it receives. The Earth's natural source of light is the sun which provides 'white' light. White light combines all of the colors in the 'visible spectrum', which is the range of colors we can see.
What color results when red is subtracted from white light?
Cyan is left when red is subtracted from white.
Why does light scattered from clouds appear white or gray quizlet?
Clouds are white because their ice crystals are large enough to scatter the light of the seven wavelengths (red, orange, yellow, green, blue, indigo, and violet), which combine to produce white light. You just studied 5 terms!
What is the color of the peak frequency of solar radiation to what color of light are our eyes most sensitive?
Peak frequency of sunlight is yellow-green, which is also the color that our eyes are most sensitive to.
What is the appearance of a material that absorbs all the light that shines on it and reflects none?
What is the appearance of a material that absorbs all the light that shines on it and reflects none? The appearance is black.
How do the light waves reflected by a blue object differ from those reflected by a red object?
The blue object reflects longer wavelength light. b.
When light reflects from a surface there is a change in its?
Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing.
What effect do clouds have on the color of the sky?
During cloudy skies the color of the sky will be a white color or a shade of gray. The thicker the clouds the grayer it will be. Light is made up on the colors of the rainbow. When the colors are put together it produces white.
What causes orange clouds?
The orange hue is caused by the same process that causes the vivid colors at sunsets. Shorter wavelengths of light (blue) are scattered quickly, leaving only the yellow-orange-red end of the spectrum. The puffy clouds that were turned orange Tuesday evening following the storm system are called mammatus clouds.
Why did the papers look white red blue and green in white light?
Because of the different frequencies of light waves, the interaction of light with materials is different as some parts are absorbed and some reflected. White light is not a single wavelength but it contains all visible colors that is why it it white.
What would be the color of a yellow object when illuminated with white light?
So a yellow object under white light will absorb most of the colours of light, and reflect back the yellow light, so we can see yellow. Because yellow light is a mixture of red and green light, yellow will also reflect red and green light.
What is the color of the peak frequency of solar radiation when it is plotted versus wavelength?
What is the color of the peak frequency of solar radiation when it is plotted versus wavelength? yellow-green.
When all colors of light are absorbed what do you see?
black As shown in the next figure, an object is seen as black if it absorbs all colors of white light.
How does light affect the color of an object?
A light source works by emitting (or outputting) various visible wavelengths of light that are then absorbed or reflected by an object. The reflected wavelengths result in the perception of color.
Which colour of light reflected by an object will make it appear blue?
The colour of an object is the colour of light which is reflected by the object. A blue object appears to be blue because it reflects blue light and absorbs other radiations.
How do objects appear when all of the colors of light are absorbed reflected selectively absorbed?
If all frequencies are absorbed by the object, then it appears black. If all frequencies are reflected, then it appears white. Selective absorption describes how some frequencies of light are absorbed while others are reflected. This results in the appearance of color.
What causes refraction light?
Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction.
What happens to the light particles when light hits an uneven surface?
For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection. Diffuse reflection is when light hits an object and reflects in lots of different directions. This happens when the surface is rough.
What do different color clouds mean?
Clouds often take on a blue-gray hue when rain droplets scatter light. They can turn ominous green when light scatters through the ice, and greenish clouds often signal heavy rain and hail, as well as a possible tornado.
What causes rainbow colors in clouds?
Rainbows form when sunlight shines through raindrops. The water acts as a prism, separating the white light into the colors of the rainbow. In rainbow clouds, ice crystals act as the prism and create the colors. The reason why rainbow clouds use ice crystals instead of rain is because of where this phenomenon occurs.
Why do clouds change color?
The colors result from a combination of Rayleigh and Mie scattering. As light passes through the atmosphere, most of the shorter blue wavelengths are scattered leaving the majority of longer waves to continue. Therefore, the predominate color of sunlight changes to these longer wavelengths.
What is the color of the white part of the paper and why does it appear so?
White surfaces A white sheet of paper reflects almost all the light that falls on it. It reflects white light because it can reflect all the colours of the spectrum that comprise white light. If red light only is shone onto a white page, the red light is reflected.
When you have colored light and a filter of a different color What do you see?
If you pass white light through a red filter, then red light comes out the other side. This is because the red filter only allows red light through. The other colours (wavelengths) of the spectrum are absorbed. Similarly, a green filter only allows green light through.
What would be the color of the yellow object when illuminated with a red light B blue light?
This means that a yellow object will appear red under red light, and green under green light. Yellow does not contain blue, so it will appear black under blue light. White objects reflect all light, so will appear to be the colour of the light on them.
