In a place `e.m` wave, the electric field oscillates sinusoidally at a frequency of `2.5xx10^(10)Hz` and amplitude `480 V//m`.The amplitude of oscillating magnetic field will be,

A

`1.52 xx 10^(-8) "wb/m"^2`

B

`1.52 xx 10^(-7) "wb/m"^2`

C

`1.6 xx 10^(-6) "wb/m"^2`

D

`1.6 xx 10^(-7) "wb/m"^2`

Text Solution

Verified by Experts

The correct Answer is:
C
Amplitude of oscillating magnetic field
`B_(e) = (E_0)/( c ) = (480)/( 3 xx 10^6) = 1.6 xx 10^(-6) "Wb/m"^2`
