Why does light refract when it passes through two different mediums having different densities?
Owen AtkinsonI would use Huygens Principle to illustrate it:
You can consider first Huygens Principle of light propagation that tells us that light propagates through secondary wavelets produced by every point on a front of a light wave.
This seems complicated but I'll try to show it with a diagram:

Hailey AlvarezLight refracts when it passes through two different mediums with different densities due to the change in speed of light as it transitions from one medium to another, according to Snell's law. This change in speed causes the light waves to bend, resulting in refraction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
