Question

Which of the following best explains why different objects are different colors? A. Different objects reflect or emit light of different speeds. B. Different objects reflect or emit light of different wavelengths. C. Some objects emit high-pressure light while other objects emit low-pressure light. D. Some objects perform photosynthesis while other objects do not.

Answer 1

Answer:

B. Different objects reflect or emit light of different wavelengths.

Explanation:

The color of an object is determined by the wavelength of the light reflected by the object. For instance: a green object appears green because it absorbs all the different wavelength of visible light, except for the wavelength corresponding to the green color, which is reflected by the object and therefore we see it green.

Therefore, the color of an object depends on the wavelengths of light that it emits/reflects.

Answer 2

The best answer is B. Atoms absorb different wavelengths of light based on stuff with electrons that I can't remember too well. Just know that it is wavelengths.
