Wavelength

Answer 1

A wavelength is the distance between two consecutive points of a wave that are in phase with each other, such as the distance between two consecutive peaks or troughs of a wave. It is usually measured in meters or other units of length and is often used to describe various forms of wave motion, such as light waves, sound waves, and electromagnetic waves. The wavelength of a wave is inversely proportional to its frequency, meaning that shorter wavelengths correspond to higher frequencies and vice versa.
