Waves is a smaller chapter but consistently delivers 2–3 questions. Standing waves on strings (fundamental and harmonics), open/closed organ pipes, beat frequency, Doppler effect — these are the workhorse topics. Wave equation applications and intensity-related questions also appear. Most of the formulas can be derived from the basic relation v = fλ.
NCERT chapters to cover
- 📘Class 11 Ch 14: Waves
- 📘Class 11 Ch 15: Oscillations
Exam tips
- 1Open pipe vs closed pipe harmonics: open pipe supports all harmonics, closed only odd. Common trick question.
- 2Doppler effect: memorize the sign convention for source/observer motion towards/away.
- 3Beat frequency = |f₁ − f₂|. Direct, predictable.
