Question

This question is only for quantum physicist .Explain it in detail.

Answer 1

the particles of light have several properties in common with the material particles and several other properties which are different from the material particles.the particles of light are called photons. a photon always travels at a speed 3×10^8 meter per sec. in vacuum.the mass of photon is not defined in the sense of newtonain mechanics.each photon has a definite energy and a definite linear momentum. let E and P be the energy and linear momentum of a photon of light . then E= hV where h is universal constant known as the plank constant and has a value 6.626×10^-34.
