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,

Options

A. `1.5xx101^(-8)Wb//m^(2)`
B. `1.52xx10^(-7)Wb//m^(2)`
C. `1.6xx10^(-6)Wb//m^(2)`
D. `1.6xx10^(-7)Wb//m^(2)`

Answer

c

Explanation

`C=(E_(0))/(B_(0))`
`:. B_(0)=(E_(0))/(c)=1.6xx10^(-6)Wb//m^(2)`
