WebMay 31, 2024 · When the speed of the particle is much less than the speed of light, non-relativistic classical mechanics faithfully describes the motion of the particle. Analogously, using wave-particle duality, the non-relativistic description of classical mechanics may be applied to describe the motion of a free electron governed by the Schrodinger equation. WebAs it is a type of light it moves at the speed of light. Speed, wavelength and frequency are closely related, as described in diagram 2: So this means that if the wave has a frequency of 100 Hz it will travel its wavelength 100 times in a second. So the speed of a wave is its frequency multiplied by its wavelength.
