Refraction: Refraction is when light bends or changes direction as it passes from one medium to another. In the case of a prism, refraction occurs as white light enters and exits the prism's surfaces.
Wavelength: Wavelength refers to the distance between two corresponding points on adjacent waves of light. Each color has its own wavelength, which determines how much it will bend when passing through a prism.
Dispersion: Dispersion is the phenomenon where white light separates into its component colors when passing through a material or object like a prism. It happens because each color's wavelength bends at a slightly different angle.
