What is wavelength?
A) It is the maximum transmission, in bit rate, across a channel.
B) It is the number of cycles that a wave repeats per second.
C) It is the distance between one peak of an electromagnetic wave and the next.
D) It is the speed at which a wave travels through a physical medium or through vacuum.

Question

Quizplus · Accepted Answer

Wavelength is defined as the distance between one peak or crest of an electromagnetic wave and the next peak or crest. It is typically measured in meters, nanometers, or other units of length.

Note: A, B, and D are incorrect. A refers to the maximum transmission rate, not wavelength. B refers to frequency, not wavelength. D refers to wave speed, which is related to wavelength but not the same thing.
