Problem: The magnetic field of an electromagnetic wave in a vacuum is Bz =(4.0μT)sin((1.20×107)x−ωt), where x is in m and t is in s.a. What is the wave's wavelength?b. What is the wave's frequency?c. What is the wave's electric field amplitude?

FREE Expert Solution

A standard electromagnetic wave equation, for a magnetic field, is given as:

Bz=B0sin(2πλx+2πvt)

a.

Comparing the equation given and the standard wave equation:

2π/λ = 1.20×107
