Which color of light bends the least during refraction?

The color of light that bends the least during refraction is red. Refraction occurs when light passes from one medium to another, causing changes in its speed and direction. The extent to which light bends is dependent on its wavelength: shorter wavelengths, such as blue or violet light, refract more than longer wavelengths like red light.

In this context, red light has the longest wavelength in the visible spectrum, which results in it bending less as it transitions between media compared to colors with shorter wavelengths. This principle can be observed in phenomena such as rainbows, where red light appears on the outside of the arc, indicating its lower degree of bending. Understanding this relationship between wavelength and refraction is crucial for grasping how various colors of light interact with materials.
