Chapter 14: Waves

Welcome to the complete revision hub for Class 11 Chapter 14: Waves — the culminating chapter of Class 11 Physics. Master wave kinematics, sound velocity derivations, boundary reflection phase shifts, standing wave harmonics in strings and organ pipes, acoustic beats, and Doppler frequency shifts.

Topics in this chapter

  1. § 14.1 Transverse & Longitudinal Waves, Wave Equation & Speed of SoundMaster progressive wave equation y = A sin(kx - wt), speed on stretched string, Newton's formula and Laplace's correction for speed of sound in air for JEE &…
  2. § 14.2 Principle of Superposition & Reflection of WavesMaster superposition principle, constructive/destructive interference, phase changes upon reflection at rigid vs free boundaries for JEE Main & NEET.
  3. § 14.3 Standing (Stationary) Waves in Strings & Organ PipesMaster stationary waves, nodes and antinodes, harmonics and overtones in stretched strings, open and closed organ pipes, and resonance tube for JEE & NEET.
  4. § 14.4 Acoustic Beats & the Doppler Effect in SoundMaster beat frequency fb = |f1 - f2|, waxing and waning, and the complete Doppler effect formula with sign conventions for moving source and observer.
