Momentum & Radiation Pressure question from JEE Main 2004 (AIEEE)

Q14JEE Main 2004 · AIEEEEasy

Momentum & Radiation Pressure

A radiation of energy $E$ falls normally on a perfectly reflecting surface. The momentum transferred to the surface is

Show answer and solution

Answer: (b)

Incident momentum $p = E/c$
Perfect reflection reverses it: $\Delta p = 2E/c$
So the answer is (b) $2E/c$ .
