When the sun passes through a thin cloud suspended with water droplets, the water droplets are like a diamond, which diffracts the passing light in different directions (diffraction refers to the physical phenomenon that waves deviate from the original straight line when encountering obstacles). Diffraction light interferes with each other, and bright light will be seen at the junction of light waves, while the light at the offset will be darker.
