What to Focus On

  • Refraction is the change in direction of light between two transparent media.
  • Light bends because its speed changes in a new medium.
  • In a glass slab, the emergent ray is parallel to the incident ray but displaced.

  • Incident ray, refracted ray, and normal lie in the same plane.
  • sin i / sin r is constant for a given pair of media.
  • This constant is called refractive index.

  • Rarer to denser: bends towards the normal.
  • Denser to rarer: bends away from the normal.
  • Normal incidence: no refraction occurs.

Common Mistakes to Avoid

Light always bends towards the normal when it enters any new medium.

A ray incident normally still bends a little because it enters a different medium.

In a glass slab, the emergent ray overlaps exactly with the incident ray.

Memory Tips

Definition of refraction

First law of refraction

Second law of refraction or Snell's law

Absolute refractive index
