Solution
The correct option is A True
The velocity of sound is affected by the density of the solid. Sound travels as successive compressions and rarefactions in
the medium. Compression is the region of high pressure
and rarefaction is the region of low pressure.
Pressure is related to the number of particles
of a medium in a given volume. More density
of the particles in the medium gives more
pressure and vice versa. Thus, propagation
of sound can be visualized as the propagation of
density variations or pressure variations in
the medium.
