Sol. The speed of sound is different for different type of mediums. The speed of sound is maximum in solids while minimum in gases. The speed of sound in air at normal temperature and pressure is 322m/s. The speed of sound depends on the density of the medium through which it is travelling. The medium which has higher density, the sound will travel faster in that medium.
