Answer:
When light is absorbed heat is generated. So the selective absorption of light by a particular material occurs because the frequency of the light wave matches the frequency at which electrons in the atoms of that material vibrate. Absorption depends on the state of an object's electron.Mar 17, 2018

The cause of absorption is the atoms present on the surface of solid posses free valency. These free Valencies attract the absorbed molecules towards itself and that is the main cause of absorption.
