Which of these produces a classic continuous spectrum?
Which of these is the classic continuous spectrum? An incandescent light (glowing tungsten filament) produces: a continuous spectrum, with the peak giving the temperature of the filament.
Which of the following can produce a continuous spectrum?
1. A luminous solid or liquid, or a sufficiently dense gas, emits light of all wavelengths and so produces a continuous spectrum of radiation. 2.
What is a continuous spectrum quizlet?
Continuous spectrum. A spectrum that exhibits all the wavelengths of visible light.
Why are molecular lines more complex than elemental spectral lines?
Why are molecular lines more complex than elemental spectral lines? Molecules can vibrate and rotate as well. Since the difference in energy between the different rotational states in a molecule is very small, many molecular lines can be observed with: radio or microwave telescopes.
What is an example of a continuous spectrum?
A rainbow is an example of a continuous spectrum. Here, the colors displayed are within the visible spectrum (between 380-760 nm). Light in this wavelength range is visible to the naked eye. Unlike the visible spectrum, light that is of different wavelengths (see the electromagnetic spectrum below) is not visible.
Is the Sun a continuous spectrum?
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.
What are some examples of a classic continuous spectrum?
A rainbow is an occurrence of a continuous spectrum. Rainbows happen when sunlight passes into raindrops and reflects off the back of them. As the light exits the raindrop, it is refracted at different angles according to its wavelength.
What is example of continuous spectrum?
A rainbow is an example of a continuous spectrum. Here, the colors displayed are within the visible spectrum (between 380-760 nm). Light in this wavelength range is visible to the naked eye. Unlike the visible spectrum, light that is of different wavelengths (see the electromagnetic spectrum below) is not visible.
What are the 3 types of spectrums?
Types of Spectra: Continuous, Emission, and Absorption.
What do you mean by continuous spectrum?
Definition of continuous spectrum : a spectrum (as of light emitted by a white-hot lamp filament) having no apparent breaks or gaps throughout its wavelength range.
Which are the atomic spectra?
There are three types of atomic spectra and they are emission spectra, absorption spectra, and continuous spectra.
What is the origin of atomic spectra?
Atomic emission spectra are produced when excited electrons return to the ground state. When electrons return to a lower energy level, they emit energy in the form of light.
Why is the continuous spectrum?
Continuous spectra (also called thermal or blackbody spectra) arise from dense gases or solid objects which radiate heat. They emit radiation over a broad range of wavelengths, thus the spectra appear smooth and continuous.

Is a rainbow continuous spectrum?
The rainbow is formed by scattering of the sunlight by water droplets present in air. The sunlight is scattered into all of its different frequencies and, therefore, can be called, a continuous spectrum.
Is fluorescent light continuous spectrum?
The incandescent light gives a continuous spectrum, while the fluorescent light gives discrete lines typical of the mercury spectrum and the phosphor.
What is continuous spectrum?
Continuous Spectrum: A continuous spectrum contains all wavelengths of light in a certain range. Hot, dense light sources like stars, for example, emit a nearly continuous spectrum of light, which travels out in all directions and interacts with other materials in space.
What are the examples of continuous spectrum?
The rainbow is formed by scattering of the sunlight by water droplets present in air. The sunlight is scattered into all of its different frequencies and, therefore, can be called, a continuous spectrum.
What is continuous spectrum in chemistry?
Definition of continuous spectrum : a spectrum (as of light emitted by a white-hot lamp filament) having no apparent breaks or gaps throughout its wavelength range.
What are the types of spectra?
The spectra can be divided into two types viz., emission and absorption spectra.
What is a continuous line spectrum?
A continuous spectrum consists of all wavelengths within a certain range. This spectrum looks like a rainbow. In contrast, a line spectrum only consists of a few wavelengths. This spectrum is made of a few colored lines on a dark background. The lines in spectra are caused by electrons moving in between energy levels.
What are examples of continuous spectra?
A rainbow is an example of a continuous spectrum. Here, the colors displayed are within the visible spectrum (between 380-760 nm). Light in this wavelength range is visible to the naked eye. Unlike the visible spectrum, light that is of different wavelengths (see the electromagnetic spectrum below) is not visible.
Why is incandescent light a continuous spectrum?
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.
Is white light a continuous spectrum?
In addition to visible light, other types of electromagnetic radiation may be spread into a spectrum according to frequency or wavelength. The spectrum formed from white light contains all colors, or frequencies, and is known as a continuous spectrum.
What are 3 types of spectrums?
Types of Spectra: Continuous, Emission, and Absorption.
What is a continuous spectrum give an example?
A continuous spectrum contains many different colors, or wavelengths, with no gaps. Perfectly white light shined through a prism causes dispersion of the light, and we see a rainbow. This is a continuous spectrum.
