Abstract

Aims/ Objectives: Using the standard momentum-energy relation in special theory of relativity, we try to show that massless moving particle with velocity of light can contribute energy and momentum to the system of objects.

Study Design: Relativistic mass energy relation.

Place and Duration of Study: Retired Professor of Mathematics, Megna Apartment , Krishnapur, between June 2020 and July 2021.

Methodology: We have considered here the mass of a system of non-interacting particles and computation of M_systerm is in terms of unit mass m. Moreover we have considered here photon having no mass. But the presence of more than one of photon contribute energy because of increment of its mass in the system. And those photons considered here are non-interacting. The M_systerm of photon is also expressed in unit mass m.

Keywords: Photon, energy, mass
