Expert Solution & Answer

Students have asked these similar questions
a) 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? [Specifically, what does this tell you about the temperature for each object that the light originates from?]
Note 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)
What have you observed relating the colors to their frequency? describe in four[4] sentences.

- An idealized radiating object does not reflect or scatter any radiation but instead absorbs all of the electromagnetic energy that falls on it. Can you explain why astronomers call such an object a blackbody? Keep in mind that even stars, which shine brightly in a variety of colors, are considered blackbodies. Explain why.arrow_forwardGo outside on a clear night, wait 15 minutes for your eyes to adjust to the dark, and look carefully at the brightest stars. 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?
