State three factors on which the speed of sound in a medium depends.
(N/A) The speed of sound in a medium depends on the following three factors:
$(i)$ Density of the medium: The speed of sound is inversely proportional to the square root of the density of the medium.
$(ii)$ Elasticity of the medium: The speed of sound is directly proportional to the square root of the elasticity of the medium. Sound travels faster in more elastic media.
$(iii)$ Temperature of the medium: The speed of sound in a gas is directly proportional to the square root of its absolute temperature (measured in Kelvin).
