In an electromagnetic wave, the electric and magnetizing field are `100V//m` and `0.265 A//m`. The maximum energy flow is:

A

`79W//m^2`

B

`13.2W//m^2`

C

`53W//m^2`

D

`26.5 W//m^2`

Text Solution

Verified by Experts

The correct Answer is:
d
Here, `E_0=100V//m , H_0=0.265A//m`
As maximum energy flow persecond per unit area
in e.m. wave will be
`(E_0B_0)/(mu_0)=E_0H_0= (100)(0.265)=26.5 W//m^2`.
