The description of a continuous spectrum and a discrete spectrum.
Answer to Problem 1PLA
A continuous spectrum contains lights of all wavelengths and a discrete spectrum contains only lights of specific wavelength.
Explanation of Solution
Spectrum is the array of colors resulting from the separation of light into component wavelengths. There are two types of spectrum, continuous spectrum and a discrete spectrum.
Continuous spectrum is the spectrum of light that contains all wavelengths and contains all colors regardless of the resolution with which the spectrum is examined.
Discrete spectrum is also known as line spectrum which contains only specific wavelength regions with respect to its source.
Conclusion:
A continuous spectrum contains lights of all wavelengths and a discrete spectrum contains only lights of specific wavelength.

Some should look slightly red and others slightly blue. The primary factor that determines the color of a star is its temperature. Which is hotter: a blue star or a red one? Explainarrow_forward

- What gives rise to spectral lines? What is happening within an atom that causes it to emite light in specific lines in a spectrum?arrow_forwardNote that a “gray” object under a red light can reflect the same light as a “red” object under white light. If we want our color perception to remain constant under different lighting conditions, should we base perceived color on (circle one) 1) the spectrum of light reaching the eye from the object (the signal)? or X the percent of light the object reflects at different wavelengths (the reflectance)arrow_forwarda) To which object corresponds this spectrum to? b) What is the source of radiation for each of the two humps? c) Why does the hump on the right hand side peak at higher wavelength than the hump on the left?
