Question

If you were to shine a flashlight beam on a perfect blackbody what would happen to the light?

Answer 1

It would all be absorbed.  It would warm the perfect blackbody and be re-radiated as infrared radiation.  So the energy would be returned to the universe as lower-frequency radiation, in all directions.

Answer 2

A black body is an object that absorbs all light that falls on it, so, assuming the blackbody is not emitting any radiation, the light would be fully absorbed and you'd still see blackness.

Answer 3

I'd say it greatly depends on what the "blackbody" is made of.

Answer 4

good question, it would create blackbody radiation

Answer 5

If it is a true black body it will warm to a temperature that causes it to radiate as much energy as it receives from the light.  The equilibrium equation will be of the form

J = α(kfTf^4 - Tb^4) = 4α(Tb^4 - kaTa^4)
