Physics · Electromagnetic Waves
A plane electromagnetic wave with electric and magnetic field amplitudes E 0 and B 0 respectively is incident on a surface. If the total energy transferred to the surface in a time 't' is 'U', then the magnitude of the total momentum delivered to the surface for complete absorption is:
- 1UB 0 E 0 2
- 2U E 0 B 0
- 3UB 0 E 0✓
- 4UE 0 B 0
Correct answer
