What happens to the speed of the light as it travels from the air, through the glass, and then through the water?

A. The speed of light slows down as it hits the glass and the water.

B. The speed of light not change as it hits the glass and the water.

C. The speed of light speeds up as it hits the glass and the water.

D. The speed of light does not change the direction of refraction

A. The speed of light slows down as it hits the glass and the water. This is due to the change in the refractive index of the medium through which light is traveling. The refractive index of the glass and water is higher than that of air, which causes the speed of light to decrease.
