What is wavelength write formula?

Wavelength is related to energy and frequency by E = hν = hc/λ , where E = energy, h = Planck’s constant, ν = frequency, c = the speed of light, and λ = wavelength.

λ = v/f . The Wavelength is expressed in m, velocity is expressed in m/s, frequency is expressed in Hz.

The term wavelength means length of the wave . Wavelength is defined as the minimum distance between two consecutive points in the same phase of wave motion.
