Em Waves Question 112
Question: A plane electromagnetic wave is incident on a material surface. If the wave delivers momentum p and energy E, then
Options:
A) $ p=0,E=0 $
B) $ p\ne 0,E\ne 0 $
C) $ p\ne 0,E=0 $
D) $ p=0,E\ne 0 $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] EM waves carry momentum and hence can exert pressure on surfaces. They also transfer energy to the surface so $ p\ne 0 $ and $ E\ne 0 $
