The magnetic field in a plane electromagnetic wave is given by
`B_(y)=2xx10^(-7)sin (0.5xx10^(3)x + 1.5 xx 10^(11) t)T`.
Write an expression for the electric field.

Explanation

`E_(0)=B_(0)C=2xx10^(-7)T xx 3 xx 10^(8) m//s =6xx10^(1) V//m`
The electric field component is perpendicular to the direction of propagation and the direaction of magnetic field. Therefore, the electric field component along the z-axis is obtained as `E_(z)=60 sin(0.5xx10^(3)x+1.5xx10^(11) t) V//m`
