For an electromagnetic wave the amplitude of the electric field is Eo, and the amplitude of the magnetic field is Bo. The source of the wave is then adjusted so that the amplitude of the E-field doubles to 2Eo. What happens to the intensity of the wave? O It stays the same. O It becomes two times larger. O It becomes four times larger O It becomes one-half as large. It becomes on-fourth as large
