When sunlight from air enters water, light that refracts most is
A)red.
B)orange.
C)green.
D)violet.
E)all refract the same amount

Question

Quizplus · Accepted Answer

When sunlight enters water, it undergoes refraction due to the change in the speed of light in different media. The amount of refraction depends on the wavelength of light, which results in the different colors of the spectrum refracting at different angles. Violet light has the shortest wavelength and therefore refracts the most, while red light has the longest wavelength and refracts the least. Therefore, the light that refracts the most in water is violet.
