All electromagnetic waves travel at the same speed in a vacuum. However, different kinds of electromagnetic waves have different wavelengths. For example, microwaves have longer wavelengths
than visible light. How is it possible for both microwaves and visible light to travel at the same speed in a
vacuum if they have different wavelengths?
A Microwaves and visible light have the same energy.
B Microwaves and visible light have different frequencies.
C The waves of visible light have less energy than microwaves.
D The distance between a point on one wave to the identical point on the next wave is the
same for both microwaves and visible light.
