Question

Factors on which the speed of a wave traveling in a medium depends :

• A. Humidity
• B. Temperature
• C. Both A and B
• D. None of these

Answer 1

The correct option is C Both A and B

Speed of a longitudinal wave in a gaseous medium is given by ,

$v=\sqrt{\gamma RT/V\rho }$ ,

where $\gamma =$ ratio of specific heats ,

$T=$absolute temperature of medium ,

$V=$ volume of gas ,

$\rho =$ density of medium (gas) ,

we can see that sped of a wave depends upon temperature and density (humidity, as presence of water vapours changes the density of gas) of the medium .
