Question

What is reason for refraction of EM waves​

Answer 1

Answer:

Refraction is caused by the response of charged particles to EM radiation. As we have seen, accelerating charges such as electrons generate EM waves. These EM waves in turn cause movement of other electrons at some distance from the generation source.

Answer 2

Answer:

Refrection is caused by the response of charge particles of EM radiation. As we have seen ascelarsting charges such as electronic generates EM waves
