Q:

Which color bends the most as light passes through a prism?

A:

Quick Answer

Violet bends or refracts the most as light passes through air and into a prism. This is because violet light in the visible light spectrum has a shorter wavelength of about 400 nanometers when compared to red at 650 nanometers.

Full Answer

The colors associated with a prism as white light passes through it are red, orange, yellow, green, blue and violet. Red light has the longest wavelength, while violet has the shortest. Violet light refracts the most and red light the least because the angle of refraction of violet light through a glass prism is a bit greater than the red light. This is due to the difference in the refractive index of red light and violet light. Violet light has a higher index of refraction in glass, at 1.532, compared to red light, at 1.513.
