The magnetic field in a plane electromagnetic wave is given by `B_(y)=(2xx10^(-7)) T sin (0.5xx10^(3)x+1.5xx10^(11)t)`.
What is the wavelength and frequency of the wave?

Text Solution

Verified by Experts

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