light rays bend away from normal as it passes from denser water to rarer air
The light will bend as it passes through.

A rainbow happens when sunlight is refracted by drops of water in the air.
The speed of light though substances is slower than the speed of light in a vacuum. As the light passes from air to water it slows and the ray's path is translated towards the normal to the air/water interface slightly.
Gets refracted more in case of glass than water as glass has higher refractive index with respect to air
That depends what it comes out of. If it passes into air from vacuum, thenits speed decreases. If it passes into air from water or jello, then its speedincreases.
it goes up into the clouds
It increases.
it slows down.
what happens is that lenses bend light in a way that makes an image
The light will bend as it passes through.
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.
