Power carried by electromagnetic wave is 3% of 100W= 3W Intensity, I is
I = 3/4 (pi) 5²
Also
I = (epsilon) C E²/2
Where c is speed of light.
Now after putting values we get
Amplitude = 2.68 V/m
I = 3/4 (pi) 5²
Also
I = (epsilon) C E²/2
Where c is speed of light.
Now after putting values we get
Amplitude = 2.68 V/m
