If the average power per unit area delivered by an electromagnetic wave is , then the amplitude of the oscillating magnetic field in EM wave is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
Average power per unit area of an electromagnetic wave is given by I=cBmax22μ0, here, c is speed of light in vacuum and μ0 is permeability of free space. Now, the amplitude of the oscillating magnetic field is…
