What is the wavelength of a wave?

It is the distance between the identical points on adjoining waveforms. The length between the two adjacent crests or troughs is wavelength in transverse waves.

1. Wavelength
It is the distance between the identical
points on adjoining waveforms. The
length between the two adjacent
crests or troughs is wavelength in
transverse waves.
The Greek letter
Lamda (λ) designates
it. Wavelength is the
ratio of the velocity
of the wave to its
frequency.
The length units used to express
wavelength are meter, centimeter,
nanometer, micrometer, and
angstroms. Out of them, the
nanometer is the most commonly
used unit to express the wavelength of
electromagnetic waves.
