Question

A plane electromagnetic wave is incident on a material surface. The wave delivers momentum p and energy E. Then:

• A. $p \neq 0,E \neq 0$
• B. $p = 0,E = 0$
• C. $p = 0,E \neq 0$
• D. $p \neq 0,E = 0$

Answer 1

Answer: (A)

$p \neq 0,E \neq 0$

Answer 2

: When plane electromagnetic wave is incident on a material surface, the wave delivers some momentum and energy to the surface and hence
