Refraction is explained by looking into a pool and seeing Snell's law in action. Unit 6 Segment M: Refraction Refraction is explained by looking into a pool and seeing Snell's law in action. We also ...

Physicists are involved in an unusually heated debate over the reality of a new kind of refraction and about the possibility of making perfect lenses. Edwin Cartlidge reports. If you think science is ...

Since their invention in 2000, exotic materials called metamaterials have revealed many uses such as perfect lenses or invisibility cloaks. But now computer simulations performed by physicists in the ...

The incident angle can be varied from 0 to 85 degrees. (In 5 degree increments using the +-5 buttons.) The index of refraction of the first medium is fixed at n=1.00. The index of refraction of the ...
