Solution(By Examveda Team)
Homi Jehangir Bhabha was an Indian nuclear physicist, founding director, and professor of physics at the Tata Institute of Fundamental Research. Colloquially known as “father of Indian nuclear programme,” Bhabha gained international prominence after deriving a correct expression for the probability of scattering positrons by electrons, a process now known as Bhabha scattering. His major contribution included his work on Compton scattering, R process, and furthermore the advancement of nuclear physics. He was awarded Padma Bhushan by Government of India in 1954.This Question Belongs to General Knowledge >> Physics
