question 25 of 25
a tree leaf appears to be green. which statement explains why the leaf isnt a blackbody radiator?
a. the leaf emits only blue and yellow light.
b. the leaf does not change temperature when it reflects light.
c. the leaf reflects light and does not emit it.
d. the leaf emits light but does not reflect it.

Explanation:

A blackbody radiator absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence, and also emits radiation. A leaf reflects green light (which is why it appears green) and does not emit light in the visible spectrum like a blackbody radiator would. Option C correctly states that the leaf reflects light and does not emit it (in the relevant context for being a blackbody radiator).

Answer:

C. The leaf reflects light and does not emit it.
