Even though an electric field `vecE` exerts a force `avecE` on a charged particle yet the electric field of an EM wave does not contribute to the radiation pressure (but transfer energy). Explain.

Text Solution

Verified by Experts

Electric field of an e.m. wave is an oscillating field. Due to it, the electric force caused by
electric field in e.m. wave on a charged particle is an oscillating one. This electric force averaged over an
integral number of cycle is zero, since its direction changes every half cycle. Hence, electric field is not
responsible for radiation pressure.
