It is always refracted, but at an angle so that it goes back into the original medium. This phenomenon is called Total Internal Reflection. The angle that this occurs at is called the critical angle.

### What three things determine how much light is refracted as it passes through a substance?

medium, reflection, and how dense the object is

### Is the angle of incidence is greater than the angle of refraction when light passes from a less dense to denser medium?

If you meant optical density by the term 'denser ' Then the answer is.... The light bends towards normal when it travels from a optically less dense medium to optically dense medium. So angle of incidence is greater than the angle of refraction

### When a wave passes from a less dense medium to a denser one most of the wave energy is?

When a wave passes from a less dense medium to a denser one, most of the wave energy is answer is reflected FALSE

### How is refraction related to light?

Refraction occurs when light passes from one medium to another. If you have your feet in a pool your legs looked bent because the light is being refracted as it moves from under the water through the air on its way to your eye.

### Wh yis light refracted when it passes from air to water?

The density of the medium through which the light is passing, changes - refracting the light.

### What is the speed of light in oil?

Einstein says that the speed of light is the same to all observers. This raises some interesting problems and his theories of relativity set out to solve them. But that aside, the speed of light is the same in olive oil and a diamond as it is anywhere else.

Refraction

yes

### Where does refraction occur?

Refraction occurs because waves move at different speeds in different bodies. Because a wave hits the other medium at an angle, part of the wave changes speed earlier than the rest, turning the waves. this is most obvious with light waves in water, but it happens with all types of waves in any change of medium.

### How is sound refracted?

Sound is a wave (of energy) in a medium [solid,liquid, or gas] (a compression wave in fact), therefore it is refracted by any change in the medium AND by the fact that it is never coherent (it never travels in only a straight line).

### What is a refracted wave?

It means that the wave changes direction when it passes from one medium to another - for example, from air to water, or from denser air to less dense air.

### How does light bend when it passes into a denser material?

The Ray of light bends toward the normal line. The reason is the light in the more dense region has slower speed. The relationship is given by the Law of Signs:sin(incident angel)/incident speed = sin(refracted angle)/dense speedSin(I)/vi = Sin(dense)/vd
