The pressure exerted by an electromagnetic wave of intensity I (watt / m ^2 ) on a nonreflecting surface is [ c is the velocity of light]

Options

  1. AI c
  2. BI c^2
  3. CI / c
  4. DI / c^2 .

Correct answer

C. I / c

Step-by-step solution

Pressure = Force / area I= Energy area-time = F S A t = F c A I / c=P
