State the factors on which the velocity of sound depends.
The velocity of sound in any gas depends upon:
The wavelength of sound only
The intensity of sound waves only
Density and elasticity of gas
The amplitude and frequency of sound
Discuss the relation between frequency and pitch of the sound wave?
A key of a mechanical piano struck gently and then struck again but much harder this time. In the second case
sound will be louder but the pitch will not be different.
sound will be louder and the pitch will also be higher.
sound will be louder but the pitch will be lower.
both loudness and the pitch will remain unaffected.

Time period (T) is related to frequency (f) as:
- T=f
T=1f
T×f=0
T×f=v
where v: speed of sound wave

Frequency of a sound wave is defined as the:
number of compressions or rarefactions produced per unit time.
distance between two valleys.
distance between two peaks.
distance travelled by wave in one second.
