Question

Sound waves A & B are travelling in two different media. Find which wave will

be travelling faster, when:

(i) A is travelling in water and B is travelling in CO2.

(ii) A is travelling in CO2 and B is travelling in hydrogen​

Answer 1

A is travelling faster in water

Answer 2

Hey dear,

● Answer -
(i) Water
(ii) CO2

● Explaination -
- Speed of the sound depends on density of the medium through which it travels.
- Higher the density higher the speed of sound.
- If we arrange given media by descending order of density -
Water > CO2 > H2

# Case I -
- As density of water is more than that of CO2, sound will travel faster in water.

# Case II -
- As density of CO2 is more than that of H2, sound will travel faster in CO2.

Hope this helps you...
