In a plane electromagnetic ware the electric field oscillates sinusoidally at frequency of `2.0xx10^10` Hz and amplitude `48Vm^(-1)`. What is wagelength of the wave ?

Explanation

Here `epsilon=48 Vm^(-1), f=2.0xx10^10 Hz C=3xx10^8 ms^(-1)` (i) Wavelength of the wave `lambda=C/f=(3xx10^8)/(2.0xx10^10) = 1.5xx10^(-2) m.`
