Speed of sound

Speed of sound:

Speed of sound is different in different mediums. In a medium, the speed of sound basically depends upon elasticity and density of medium.

Speed of sound is maximum in solids and minimum in gases.

When sound enters from one medium to another medium, its speed and wavelength changes but frequency remains unchanged.

In a medium, the speed of sound is independent of frequency.

Effect of pressure on speed of sound: The speed of sound is independent of pressure i.e. speed remains unchanged by the increase or decrease of pressure.
