Question

State two factors on which the speed of a wave travelling in a medium depends

Open in App
Solution

Dear Student,

The sound is the waveform which is propagated with the collisions of the particles in the medium through which it travels.
Sound waves depend upon the following factors:
1. Density Of The Medium:
As we know that sound waves need a particular medium to propagate, therefore it significantly depends upon the nature of the medium through which it travels. If the medium is dense, it means that the molecules are closely packed with each other. Hence a large amount of force is required to vibrate the molecules to produce a sound wave. Thus the speed of sound decreases with an increase in the density of the medium and vice versa.
2. Temperature Of The Medium:
Sound waves are directly proportional to the temperature of the medium through with it travels. If the temperature is high as in deserts, the speed of sound is more and if the temperature is low as in snowy areas, the speed of sound would be slow.
