Prism Light Deviation Explained
When white light passes through a prism, it splits into its constituent colors due to a phenomenon called dispersion. Each color bends at a slightly different angle.
The amount a color deviates depends on its wavelength. The prism's material refracts light, and the refractive index varies slightly for different wavelengths.
- Colors with shorter wavelengths (like Violet) have a higher refractive index in the prism material and therefore deviate more.
- Colors with longer wavelengths (like Red) have a lower refractive index and therefore deviate less.
Red light possesses the longest wavelength in the visible spectrum. As a result, it experiences the least amount of bending or deviation when passing through the prism.
Thus, the color that deviates the least is Red.
