1Loudness, pitch, and quality depend on amplitude, frequency, and waveform.
2Frequency determines pitch while amplitude affects loudness in a sound wave. Waveform diagrams show these characteristics visually, with more peaks and troughs indicating higher frequencies and greater distance between them showing larger amplitudes. In exams, questions often ask you to explain the relationship between frequency, amplitude, pitch, and loudness. Remember that increasing frequency raises pitch but does not affect loudness directly; similarly, louder sounds have higher amplitudes without necessarily changing their pitch.
3Characteristics of Sound should be revised by linking the physical idea, the formula or diagram cue, and the final result.
4Keep the physical observation and the reason separate, then connect them clearly.
