Question

The speed of sound in air is 320 ms⁻¹ and in water it is 1600 ms⁻¹.
(i) Find the ratio of distance travelled by sound in air and in water.
(ii) Find the ratio of time in air and water to travel the same distance.

Answer 1

Time taken by the sound to travel 800 m is water is 0.5 s

Explanation:

Distance traveled by the sound in air is 800 m.

2) Time taken by the sound to travel 800 m is water is 0.5 s

Explanation:

Speed of sound is air = 320 m/s

Time taken by the sound wave in air = 2.5 seconds

Speed = Distance / Time

• 1) Distance traveled by the sound in air:

Distance=320 m/s\times 2.5 s = 800 m

• 2) Speed of sound in water = 1600 m/s

Distance traveled by the sound is water =- 800 m (given)

Time=  Distance / Speed = 800 m / 1600 m/s = 0.5 s

Time taken by the sound to travel 800 m is water is 0.5 s
