Question

Light is a electromagnetic wave . In the presence of light charged particel can experience force and why ?​

Answer 1

Answer:

You will get many answers if you get any elementary plasma physics book. These books discuss the propagation of electro-magnetic waves in ionised media.

Photon has kinetic mass mp= h nu/c² ( nu is frequency, c is velocity of light and h is Planck constant. This mass is attracted by any massive bode. The force far away from the center of the massive object can be guessed to be equal to

F= mp G M /R².. This force bends the light. If it propagating perpendicular to the direction of force, then the bending will be approximated by

tan theta= mp *velocity ( F*time). Here theta is the angle of bending. This is approximated.

The gradient in refractive indices can bend the ray, slow or speed up the ray. This picture is based on the intensity of the wave. If the intensity is very large then the nonlinear effects will lead to wave-wave scattering. This is responsible for nonlinear optics.
