An electromagnetic wave is propagating in vacuum along x-axis,which is produce by oscillating charge of frequeny `3xx10^(10)Hz` amplitude of magnetic filed `(B_(0))` is `1 xx10^(-7)T` along z-axis. Find ?
(a) Wavelengths of the wave
(b) Propagation constat of the wave
(c) Equation for oscilating electric field and magnetic field.

Explanation

(a) `lambda(C)/(f) =(3xx10^(8))/(3xx10^(10))=1 xx10^(-2)m`
(b) `K=(2pi)/(lambda)=(2xx3.14)/(10^(-2))=6.28xx628m^(-1)`
(c) `E=CB_(0)sin (2pixx3xx10^(10)t-628x)`
`vecE=30 sin(6pix10^(10)t=-628x)hat j (N)/(C)`
and ` vecB=1xx10^(-7)sin (6pixx10^(10)x)hatk T`
