Web1. d. They are both carried by electromagnetic waves. Light and sound are both forms of energy that are carried by electromagnetic waves. This means that they have the ability to travel through the air, water, or even a vacuum without any hindrance. This means that they can both travel long distances and can even penetrate objects. WebElectromagnetic radiation can be described by its amplitude (brightness), wavelength, frequency, and period. By the equation E=h\nu E = hν, we have seen how the frequency of a light wave is proportional to its energy.
