In a plane electromagnetic wave, the electric field oscillates sinusoidally of a frequency of `3 xx 10^(10)Hz` and amplitude `50V m^(-1)`. What is the wavelength of wave?

Options

A. 0.01m
B. 0.05m
C. 0.1m
D. 0.25m

Answer

A

Explanation

`v=3 xx 10^(10)Hz, C=3 xx 10^(8)m//s`, As wavelength `lamda = (C )/(v)= 0.01m`
