Question

how speed of sounddepends upon medium explain​

Answer 1

The velocity of mechanical wave depends on elasticity and inertia of the medium.

Velocity of a transverse wave along a stretched string

Let us consider a string fixed at one of its ends and tension be applied at the other end. When the string is plucked at a point, it begins to vibrate.

Consider a transverse wave proceeding from left to right in the form of a pulse when the string is plucked at a point as shown in Fig. 7.4. EF is the displaced position of the string at an instant of time. It forms an arc of a circle with O as centre and R as radius. The arc EF subtends an angle 2θ at O.

Answer 2

SPEED OF SOUND DEPENDS ON MEDIUM MEDIUM AS IT NEEDS MEDIUM FOR PROPAGATION.
