Sound as a longitudinal wave, pitch and loudness, and echoes; the Doppler treatment is enrichment.

Mastery checklist

Know what success looks like.

  1. 01

    Label the wave or ray diagram with the quantities and boundary conditions that matter.

  2. 02

    Relate frequency, period, wavelength, speed, phase, or angle using the correct model.

  3. 03

    Predict how the observable pattern changes when one controlled variable changes.

Exam lens

Build, apply, check.

3.4 Sound sits inside Waves. Build the concept first, then practise selecting a model, showing working, and checking the final result.
