I guess a lot of people have a concept of what refraction is. I don’t know if you’ve had a conversation with a friend, a relative, or even a stranger. A lot of people that I know have heard the idea of refraction and have never stopped to think about it. There are many misconceptions of what it is. You can either read through the article to get a better understanding, or you can try to do it on your own.

Refraction is when light passes through different materials, or other substances. For example, water and air can refract light, but when you add another substance, it changes the path of the light. Refraction occurs when you have layers of different substances, and light refracts from one layer to another.

The refraction phenomenon is the same in many different substances, so the same explanation can apply to all of them. This phenomenon is usually explained by saying that light is a wave and when light passes through the different layers of various substances, the waves of light pass again, but in a different path.

The refraction phenomenon is caused by layers or substances on a given surface of a substance, but because light bounces off of the different layers, refraction occurs. The idea is that when light passes through one layer of a substance, it is refracted. When light passes through two layers, it actually passes through both layers, but the light is refracted again in a different way.

You’ll be able to pass through a layer of water in the ocean, and you won’t be able to see through the water. But you’ll be able to see through the refraction, as water is actually a layer of a substance. The same concept applies to any substance that has layers (like air). When light passes through a layer of that substance, it refracts.

It also means that there is no such thing as a perfect substance. For example, the air that we breathe is a perfect substance, but it is not a perfect substance. So we can breath without a problem, but we do have to breathe through a straw, and we can also breathe through a tube, but we can also breathe through a glass, and we can breathe through a wall, but we can also breathe through a window.

For a perfect substance, it would have to be air, but the air we breathe isn’t perfect either. In fact, it could be 100% air and still be a perfect substance.

This is a great example of how a perfect substance is not a perfect substance. No one can breathe a perfect substance and still be a perfect substance, not even the best of substances.

This is why I’m not a fan of the idea of a perfect substance. If you look at the atom, every atom is a perfect substance, but the reality is that we’re all a little bit in the dark here. Maybe we just need to stop using our brain for a bit, and start using our body for a bit. The right food for the right person, and a bit of exercise every day would do us just fine.

A perfect substance would be something that could replicate itself in every single atom, and yet still be a perfect substance. It would be the perfect substance that is everywhere without ever being anywhere. This is not something that can be done.
