How is velocity of the sound affected due to presence of moisture in air?
The velocity of sound:
V=γPdwhereγisconstantforagasPisthepressureofthemediumdisthedensityofthemedium
Hence, the velocity of sound increases as the presence of moisture increases in air.
How do the following factors affect, if at all, the speed of sound in air :
(i) the frequency of sound,
(ii) the temperature of the air,
(iii) the pressure of air,
(iv) moisture in the air?
