Superposition of Waves — Class 12 Maharashtra HSC Physics revision notes
A 6-page visual revision sheet for Superposition of Waves, written for Class 12 Maharashtra HSC Physics. Formulas, diagrams and the traps that cost marks, laid out to be read the night before rather than the term before. Free, and it opens inside CapCompass.
What this Superposition of Waves sheet covers
- progressive wave
- Progressive waves
- reflection of waves
- The principle of superposition
- interference
- Interference of two waves, same frequency
- resultant amplitude, phase difference phi
- waves in phase, φ = 0
- waves out of phase, φ = π
- stationary waves
- Formation of stationary waves
- Nodes and antinodes
- nodes: zero amplitude, permanently at rest
- antinodes: maximum amplitude A
- distance from a node to the next antinode
- Progressive waves vs stationary waves
- Stationary wave
- harmonics
- overtones
- Harmonics and overtones
- Free vibrations, forced vibrations and resonance
- End correction
- Air column closed at one end
- fundamental frequency, length L
- allowed frequencies
- Air column open at both ends
- vibrating string
- sonometer
- Laws of a vibrating string
- fundamental frequency, tension T, mass per length m
- law of length, T and m fixed
- law of tension, l and m fixed
- law of linear density, T and l fixed
- beats
- two sources, close frequencies n_1 and n_2
- period of beats
- Applications of beats
- Symbols
- Traps that cost marks
- Tricks that save time
How CapCompass uses this sheet
These notes are not a standalone PDF. CapCompass plans Physics chapter by chapter against your real exam dates and free hours, and when the plan reaches Superposition of Waves the sheet opens inside the study block itself — at the page covering the sub-topic that block is on, with the timer still running. Revision arrives at the moment the plan says revise, instead of having to be gone looking for.
