Question

Which of the following statement about sound waves is correct?

(A) The travel of sound waves is not affected by the medium through which it
travels.
(B) Sound waves travel faster in air than in liquid.
(C) Sound waves travel faster in solid than in air.
(D) Sound waves cannot travel through a solid.

Answer 1

Answer:

(B) Sound waves travel faster in air than in liquid.

Explanation:

Sound waves travel faster in a solid than in liquids and gases. Because the speed of the sound depends on the density of the medium in which it propagates. Higher the density of the medium, the faster the sound travels.

Answer 2

Answer:

Option C is the right option.

Explanation:

Option A is false because speed of sound is affected by the medium in which it travels.

Denser the medium higher is the speed of sound in it.

Option B is false because liquid is denser than air so sound will travel faster in liquid.

Option C is true because solid is denser than air so sound will travel faster

in solids than air.

Option D is false because light travels in all the three mediums.
