1.	Write three characteristic features in photoelectric effect which cannot be explained on the basis of wave theory of light, but can be explained only using Einstein's equation.
Answer» The three characteristic features which can't be explained by wave theory are : (i) Kinetic energy of emitted electrons are found to be independent of intensity of incident light. (ii) Below a certain frequency (threshold) there is no photoemission. (iii) Spontaneous emission of photo-electrons.

Answer»

The three characteristic features which can't be explained by wave theory are :

(i) Kinetic energy of emitted electrons are found to be independent of intensity of incident light.

(ii) Below a certain frequency (threshold) there is no photoemission.

(iii) Spontaneous emission of photo-electrons.
