Final answer:
Blue light undergoes the most refraction compared to other colors when passing from air into glass due to its shorter wavelength.
Step-by-step explanation:
When light passes from air into glass, the amount of refraction it undergoes depends on its wavelength. Refraction is a phenomenon that causes light to bend when it passes from one medium to another due to the change in its speed. The general rule is that colors with a shorter wavelength bend more than those with a longer wavelength. In the visible spectrum, blue light has a shorter wavelength compared to green, yellow, and orange.
Therefore, the correct answer is D. blue. This is because blue light goes through the most refraction due to having a shorter wavelength. When light enters a denser medium like glass from a less dense medium like air, each color refracts differently because each has a different wavelength.
