Question

The pitch of sound depends upon the
(a) amplitude
(b) wave velocity
(c) wave length
(d) frequency

Answer 1

d) frequency
mark me as 3

Answer 2

Answer:

(c) wave length

Explanation:

Pitch is the human perception of frequency, which depends on the wavelength and the speed of sound in the medium. The frequency is affected by changes in pressure, humidity and temperature. Pitch does not have a linear relation to frequency.

It is measured in Hertz (Hz). Hertz are ‘cycles per second'. The higher the number of Hz the higher the pitch of a sound.
