SATHEE: Optics Question 182

Optics Question 182

Question: A plane electromagnetic wave of wave intensity 6 W/m2 strikes a small mirror area 40 cm2, held perpendicular to the approaching wave. The momentum transferred by the wave to the mirror each second will be

Options:

A) $6.4 \times 10^{- 7} k g - m / s^{2}$

B) $4.8 \times 10^{- 8} k g - m / s^{2}$

C) $3.2 \times 10^{- 9} k g - m / s^{2}$

D) $1.6 \times 10^{- 10} k g - m / s^{2}$

Show Answer

Answer:

Correct Answer: D

Solution:

Momentum transferred in one second $p = \frac{2 U}{c} = \frac{2 S_{a v} A}{c} = \frac{2 \times 6 \times 40 \times 10^{- 4}}{3 \times 10^{8}}$

$= 1.6 \times 10^{- 10}$ kg-m/s2.
