Question

explain four factors on which speed of sound depends​

Answer 1

Speed of sound depends primarily on the density and viscosity of the medium through which it propagates. So temperature, humidity (if non liquid medium) and pressure are also factors as they impact the density and viscosity of the medium, especially if the sound wave propagates through fluids.

Answer 2

Some measure factor on which speed of sound(in air medium) depend are: 1.Temperature (velocity of sound is directly proportional to square root
