Question

the electromagnetic waves in free space are represented by electric field vector, =10 (107−10) , then find magnitude and direction of the magnetic field vector.

Answer 1

Answer:

then, wave propagation occurs in −x direction.

Amplitude is A, wave number is k, wavelength is 2π/k and wave velocity is ω/k

Hence,

A=10V/m

c=ω/k

/k

k=0.033 rad/m

λ=2π/k=60π=188.4m
