Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. Wave Theory of Light and Huygens Principle, 2. Reflection and Refraction from Wave View, 3. Superposition, Coherent Sources, and Interference.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 95 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 Wave Optics after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Descartes gave the corpuscular model of light in 1637 and derived Snell's law.
  • Huygens put forward the wave theory of light in 1678.
  • Foucault's 1850 experiment supported the wave model.
  • A wavefront is a surface of constant phase.
  • A spherical wave comes from a point source.
  • A plane wave is obtained far from the source.
  • Snell's law from Huygens principle is n1 sin i = n2 sin r.
  • When light bends toward the normal, speed is lower in the second medium.
  • When light enters a denser medium, wavelength and speed decrease but frequency remains the same.

Common Mistakes to Avoid

If light bends towards the normal, its speed must be greater in the second medium.

Frequency changes when light enters another medium, because speed changes.

The corpuscular model of light predicts that light slows down in a denser medium.
