Yes, that's correct. The amount of bending a wave experiences when it refracts depends on the change in speed the wave undergoes as it enters a different medium. This change in speed causes the wave to bend either towards or away from the normal line at the interface between the two mediums.

What does relative refractive index tells?
The relative refractive index describes the change in speed of light as it moves from one medium to another, indicating how much the light bends or refracts at the interface of the two media. It is calculated as the ratio of the speed of light in a vacuum to the speed of light in the medium in question. The larger the relative refractive index, the more the light is bent or refracted as it enters the medium.
Why light bends when it passes from air to water?
Light bends when it passes from air to water due to a change in the speed of light. This change in speed is caused by the difference in optical density between air and water. As light travels from a less dense medium (air) to a more dense medium (water), it slows down and changes direction, resulting in the bending effect known as refraction.
What happens when light goes from a less dense medium to a more dense medium?
When light goes from a less dense to a more dense medium, it slows down and changes direction. This change in speed and direction is known as refraction. Refraction occurs because the speed of light is different in different mediums, causing the light waves to bend as they enter the more dense medium.
Which colour refracts more in a prism yellow or blue?
Blue refracts the most in a prsm than yellow
What can you tell us about the refractive index?
"The refractive index is a measure of how much light bends or refracts when it is passed through a certain medium. The higher the numerical value of the refractive index, the more that light suffers from refraction."
Refraction causes light to do what?
Refraction is the bending of light when it passes from a dense medium to a differently dense medium. Light therefore finds it easier/more difficult to travel and the speed changes accordingly, which is why it bends.

What does the lens do in a telescope?
It refracts (bends) light into a focal point

What part of your eye refracts light?
The retina which is where the image from the eye lens is focused. The retina is the reflective part of the eye. That's why cat's eye reflect so well, their retina are more exposed in the night because their pupils (or whatever they are in a cat) open wider than ours exposing more of that mirror at the back, the retina. Meeow!

Does light change speeds if the source is moving?
The speed of light is constant in its reference plane. You could never observe light moving more slowly, except when it refracts through a transparent medium.
How does an increase in speed affect an object?
its position changes more rapidly
What way does the light bend if it is travelling from a more to less dense medium?
The light bends away from the normal line when traveling from a more dense medium to a less dense medium. This phenomenon is known as refraction and occurs because the speed of light changes as it moves from one medium to another, causing it to change direction.
Why is light rafracted when you see a mirage?
Layer of air at different temperatures refracts ("bends") light at different angles. Cold air is more dense than warm, and refracts light at a greater angle. Actually, it is the boundary between layers that does the refracting--poke a stick into a pool of water [or a pencil into a bowl of water] and observe the "broken" appearance. In the atmosphere, this can cause an image to appear "above" its actual location, usually upside down.
