Color is a result of the absorption and reflection of light. a shirt appears a color because it reflects that color of light. a shirt appears black when it absorbs all wavelengths of light. why does a shirt appear white outside on a sunny day? a. the light is transmitted through the shirt, so no color appears. b. the shirt absorbs the sunlight, so it appears white. c. all the light is reflected, so the shirt appears white. d. the sunlight refracts when it hits the shirt, so the shirt appears white.

C. All the light is reflected, so the shirt appears white.

Explanation:

In optics, "white" corresponds to the presence of all colors together, while "black" corresponds to the presence of no colors at all.

As said in the text of the problem, the shirt appears black when it absorbs all wavelengths of light: in this case, no color is reflected, so the shirt appears black to our eyes (absence of colors).

The opposite situation occurs when the shirt reflects all the different wavelengths of light, instead of absorbing them. In this case, all the colors are reflected, so our eyes are able to see all the colors together (and the mix of all colors appear white): so the shirt appears white when all the light is reflected.
