The speed of red light is slower in air and water than in a vacuum. The frequency, however, does not change when red light enters water. Does the wavelength change

Sagot :

Given that the speed of red light is slower in air and water than in a vacuum, but its frequency does not change ;

The wavelength changes (decreases) as the light enters water.

Characteristics of light wave in water and air

When light such as red light travels from air into water, the speed of the light will change, but the frequency of the light traveling through vacuum, water and air will remain constant. But as light travels from air into water, the wavelength will decrease.

Hence, we can conclude that the wavelength changes (decreases) as the light enters water.
