Which factors determine the quality of the note?
Wave form
The explanation for the correct option:
The explanation for the incorrect options:
Option A: The number of completed wave cycles per second is referred to as frequency.
Option B: The wavelength of light is defined as the distance between two wave motion crests or troughs.
Option D: The time period is the time taken by a complete cycle of the wave to pass a point.
Two notes of the same pitch and intensity performed from different instruments don't sound identical because the waveforms fluctuate and thus the quality or tone differs.
Hence, option (C) is correct.
