Question 204: EM waves

Question

A radiation of energy 'E' falls normally on a perfectly reflecting surface. The momentum transferred to the surface is (C = Velocity of light)

Accepted Answer

Momentum transferred to the surface
= change in momentum
= P
f
- P
i
= $$ + {E \over C} - \left( { - {E \over C}} \right)$$
= $${{2E} \over C}$$

Answer

$${{2E} \over {{C^2}}}$$

Answer

$${E \over {{C^2}}}$$

Answer

$${E \over C}$$

Answer

$${{2E} \over C}$$
