When is the light with longer scattering wavelength easy to scatter?

Due to the inhomogeneity of the medium, the phenomenon that light deviates from the original propagation direction and scatters sideways is called the scattering of light by the medium. The scattering of fine particles follows Rayleigh's law: the intensity of scattered light is inversely proportional to the fourth power of wavelength. When sunlight passes through the atmosphere, violet light, blue light and cyan light with shorter wavelength are most easily scattered, while red light, orange light and yellow light with longer wavelength are less scattered.
