AssertionSound waves do not travel through vacuumReasonSound waves are mechanical waves which require a medium for their propogation (1) Both assertion and reason are correct and the reason is the correct explanation asseration (2) Both assertion and reason are correct but the reason is not the correct explanation asseration (3) Asseration is correct but reason is not correct (4) Both asseration and reason are incorrect

Answer:

Sound waves are mechanical waves. In comparison to electromagnetic waves, they involve a propagating medium.

The velocity of the sound varies in the different medium as given below.

  • Sound travels in solids at a rapid rate than air, fluid or vacuum.

  • Through denser media, sound travels at a higher rate. The solid density is higher than the air, liquid and vacuum densities.

  • The velocity of sound in Vacuum medium < Gas medium < Liquid medium < Solid medium.
