We measure electromagnetic waves in three ways: (3 points) a: amplitude, frequency, and wavelength b: amplitude, speed, and wavelength c: speed, frequency, color d: frequency, color, wavelength

The answer to this question is letter A. Electromagnetic waves travel as fast as light. They are represented as wave functions. The parameters involved are: amplitude, frequency and wavelength. The amplitude is the maximum displacement of the wave from equilibrium. Wavelength is the distance from one amplitude to the next. Frequency is the number of cycles (1 wavelength) per second.
