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`.
What is the wavelength and frequency of the wave ?

Explanation

Comparing the given equation with
`B_(y)=B_(0)sin[2pi((x)/(lambda)+(t)/(T))]`
We get , `lambda=(2pi)/(0.5xx10^(3))m=1.26 cm,`
and `(1)/(T)=v=(1.5xx10^(11))//2pi=23.9` GHz
