Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Refraction of Light and Glass Slab Activity, 2. Laws of Refraction and Refractive Index, 3. Common Media and Velocity Relations.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 45 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Refraction of light after a week. Use flashcards for quick recall and try past exam questions on this chapter.

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.
