In this activity you will observe how the index of refraction of different materials helps us to see (or not see!) the objects as light passes through them! Two clear glass jars, tall bowls or ...

Rather than always traveling in a straight line, like you'd expect, light can change directions based on the medium its ...

In this activity you will turn a spoon blackened ... Without this bending of light due to refraction we would not be able to use lenses or magnifying glasses. If you're enjoying this article ...

In this required practical activity ... angle of incidence increases the refracted light will bend from a bigger initial angle, and so the angle of refraction will also be bigger.

Scientists have long sought to control light in ways that appear to defy the laws of Nature. Negative refraction -- a phenomenon where light bends in the opposite direction to its usual behavior ...
