Refractions occur when light passes through a transparent medium, such as glass or plastic.…The individual photons of light are actually slowed down as they passed to the…medium, which creates distortion.…This distortion is what we see visually as refraction.…I'll take a look of the scene.…I have a couple of teapots here.…I've created a render.…Let's take a look at the render here.…This teapot on the left here is completely transparent, but it shows no refraction.…In other words, you can see the checkerboard pattern through the transparent…surface is still perfectly undistorted.…
It looks just like the texture in the background.…The only difference between this surface on this teapot here and this teapot is…that I've turned on refractions for this surface.…So now you can see that the checkerboard pattern is actually distorted.…As we look through the surface, we can see this distortion.…That's known as refraction.…I've created another diagram here to illustrate this point using dynamics.…Imagine this is a transparent surface that has a fare amount of thickness it.…
