What happens to light when it is captured by a material?<br> plz, help meeeee!!!!! TwT

Nat2105 [25]

During absorption, frequency of the incoming light wave is either near or at the energy level of the electrons in the matter of the material. The electrons will absorb the energy of the light wave and change their energy state.

Hope that helps! :)
