Question

Prove E=pc using Planck's Constant?

Answer 1

Answer:

Explanation:

First of all, the only particles with rest mass is zero are the radiations like light,where their velocity is light velocity C,in this case these quanta are relativistic,and any particle with speed close to C is a relativistic particle,where its energy is,

E^2=P^2 C^2+ m^2C^4

Where m is the rest mass,and since m is zero,so E=PC = MC^2,

Don`t mix between rest mass and mass gained by moving relativistacally which is given as M=E/C^2
