In physics, the wavelength of a sinusoidal wave is the spatial period of the waveâthe distance over which the wave's shape repeats,[1] and thus the inverse of the spatial frequency.
Let us consider any two points in the wave at which the shape of the wave repeats. This distance between those two points is called Wavelength. Hence the Wavelength is defined as the difference between two points of same phase. The Wavelength Symbol is given by $\lambda$.
