Question

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

Explanation:

A black - body radiator absorbs all incident electromagnetic radiation and re - emits it according to its temperature. A green leaf appears green because it reflects green light and does not emit light on its own under normal conditions. This goes against the property of a black - body radiator which only emits radiation and does not reflect external radiation.

Answer:

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