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

Text Solution

Verified by Experts

Electric field of electromagnetic waves is an oscillating field and so the electric force caused by it on charged particle. This electric force averaged over an integral number of cycles is zero since its direction changes every half cycle. Hence electric field is not responsible for radiation pressure.
