light rays bend away from normal as it passes from denser water to rarer air
The frequency of light remains constant as it changes medium from air to water. However, the speed and wavelength of light will change, causing it to bend or refract.
Light bends towards the normal when it goes from air into water due to the increase in optical density of the medium, leading to a decrease in speed of light and hence bending towards the normal.
It gets faster. As a result, it also changes its direction.
Light bends away from the normal (the line perpendicular to the surface) when it goes from water to air. This bending is known as refraction and occurs due to the change in speed of light as it moves from one medium to another with a different refractive index.
The frequency of light remains constant when passing from air to water. However, the speed of light changes due to the change in the medium, causing the wavelength to change. This change in wavelength results in the light bending or refracting at the interface between air and water.

it goes up into the clouds
it slows down.
It increases.
what happens is that lenses bend light in a way that makes an image
The speed increases.
slowdown

The speed of light depends on the electrical properties of whatever substance it's in. It has nothing to do with what substance it used to be in before, or what substance it's going into next. -- If it goes from air into vacuum, its speed increases. -- If it goes from air into water, its speed decreases. -- If it goes from water into air, its speed increases. -- If it goes from water into diamond or jello, its speed decreases.
If the speed of light were the same in air and water, then the pencil would appearstraight, NOT broken. The beginning of the simplest explanation of why it doesappear broken is the fact that the speed of light is different in air and in water,and that causes light to bend when goes from one into the other.
