A standard electromagnetic wave equation, for a magnetic field, is given as:
Comparing the equation given and the standard wave equation:
2π/λ = 1.20×107
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?
