Prism

As light traverses two mediums with distinct refraction indices, it changes direction, with part of its energy being transferred to the denser medium. This change depends on the refraction index and the angle of incidence. In prisms, light decomposes into its color components due to deviation at different angles, resulting in a rainbow. The phenomenon of refraction occurs when light, passing from one material to another with different speeds, deviates from its path. In white light, which is a mixture of all colors of the spectrum, each color, having a distinct wavelength, is refracted uniquely.
