In si units, the electric field in an electromagnetic wave is described by ey = 112 sin(1.40 107x − ωt). (a) find the amplitude of the corresponding magnetic field oscillations. µt (b) find the wavelength λ. µm (c) find the frequency f. hz

Explanation:

The electric field in an electromagnetic wave is described by:

The general equation is given by :

Here,

The amplitude in electric field is

Propagation constant,

is the angular frequency

(a) The amplitude of the corresponding magnetic field oscillations is given by :

(b) We know that the propagation constant is given by :

(c)

answer: the answer is a
