Problem: A sinusoidal electromagnetic wave having a magnetic field of amplitude 1.25 μT and a wavelength of 432 nm is traveling in the +-direction through empty space.What is the amplitude of the associated electric field?

FREE Expert Solution

Speed of electromagnetic waves is related to Electric field and Magnetic field by:

c=EmaxBmax

Bmax = 1.25 μT(10-6T/1μT) = 1.25 × 10-6 T
