The relationship between wavelength and energy is that the greater the wavelength, the smaller the photon energy. The relationship between wavelength and energy mentioned here refers to the relationship between wavelength of light and photon energy. In short, the greater the wavelength, the smaller the photon energy. This is because photon energy is proportional to the speed of light (usually expressed as f or v). Because the wavelength of red light is large and the wavelength of violet light is small, the photon energy of red light is small and that of violet light is large. It is particularly important to note that what we are talking about here is the energy of a photon, not the comparison of the energy of a beam of light.

Mathematical relationship between wavelength and energy and its solution;

The mathematical relationship between wavelength and energy is λ=u/f, where u is the wave velocity and f is the frequency. The solution process is as follows: (1) The wavelength input is equal to the product of the wave velocity u and the period t, that is, λ=uT. (2) frequency f =1/t: t =1/F. (This is the relationship between perimeter and frequency) (3) T= 1/f is substituted into λ=uT, and λ=u/f is obtained. Wavelength refers to the displacement between two relative equilibrium positions in the wave pattern along the propagation direction of the wave. The wavelengths of shear wave and longitudinal wave represent different meanings. In shear waves, wavelength refers to the phase difference between two adjacent phases.
