As your friend has not done B.Sc. in Physics or has not studied Physics at Graduation level, he will not be able to take admission in M.Sc (Physics).
However, I am mentioning some UGC-recognized universities which offer M.Sc(Physics) by correspondence mode:-
(a) IGNOU, Central University
(b) Nalanda Open University, Bihar
(c) Vidyasagar University, West Bengal
(d) Annamalai University, Tamil Nadu
(e) Bhoj Open University, Madhya Pradesh
University must be chosen considering the state of residence.
"If you are killed in action, you go to Heaven. If you win, you rule this Earth (as beautiful as Heaven). That is why, O son of Kunti, take a firm resolve and fight!"-- Shrimad Bhagwad Gita
