The wavelength of electron is 395 nm.
The distance that separates two subsequent peaks or troughs of a waveform is known as its wavelength. It is measured in the wave's direction.
The distance a wave travels between its crests or troughs is known as its wavelength (which may be an electromagnetic wave, a sound wave, or any other wave). The wave's crest is its highest point, while its dip is its lowest. Because a wavelength represents a distance or length, it is expressed in length units like metres, centimetres, milimeters, nanometers, etc.
Light's wavelength changes with colour, or it differs for each hue. While violet has the shortest wavelength, red has the longest. UV light has a shorter wavelength than violet light.
