UPSC CDS-2 – 2022
The pitch of a sound wave is determined by its frequency. Higher frequency corresponds to a higher pitch, and lower frequency corresponds to a lower pitch.
– Pitch is the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.
– Frequency is the number of vibrations per unit of time.
Loudness of a sound is related to its amplitude, not frequency. Speed is the rate at which the sound wave travels through a medium and is dependent on the medium’s properties.
