Suppose that the electric field amplitude of an electromagnetic wave is `E_(0) = 120 N//C` and that its frequency is ν = 50.0 MHz. (a) Determine,`B_(0) omega, k, and lamda`. (b) Find expressions for E and B.

Explanation

(a) `400 nT. 3.14 xx10^(8)" rad//s"1.05" rad//m ".6.00 m`.
(b) `E={(120 N//C) sin (1.05" rad/m ")]x-(3.14xx10^(8)" rad/s")t]} hat J`
`B={(400 nT) sin (1.05" rad/m")]x-(3.14xx10^(8)" rad/s")t]} hat K`
