Question

Name two properties of light radiation which indicate its particles like nature

Answer 1

Hello Friend !


The Photoelectric effect and the black body radiation are the two characteristics of the light radiation.
These two characteristics depend on the structure of the atom and thus explain its particle like behaviour.
atoms and molecules could emit energy only in the form of discrete quantities and not in a continuous manner.

E =nhν

which suggests the particles nature of the light. 


Hope this helps !!
