Answer

The explanation of photoelectric effect

Explanation:
Einstein proposed the special theory of relativity and the general theory of relativity. Also, he gave a explanation to quantum theory. According to Nobel committee other theories were in controversy.
The classical theory could not explain photoelectric effect satisfactorily. The photoelectric equation given by Einstein explains photoelectric effect satisfactorily.
Hence, Einstein was awarded Noble prize for the explanation of photoelectric effect.
