If the depth of the sea is 1.125 km, the time taken for the reflected sound to reach the sonar is _________ s.
(velocity of sound in water is `1500 ms^(-1)`)

A

`1`

B

`1.5`

C

`2`

D

`2.5`

Text Solution

Verified by Experts

The correct Answer is:
B
Speed of sound in water
`= ("Distance covered by sound")/("Time")`
`"Time " = ("distance covered by sound")/("speed of sound in water") = (2 xx 1125)/(1500) = 1.5 s`

Chanukya was eager to know the time taken by sound to travel the same distance in water and air. So, he set a body on vibration with a frequency of 250 Hz in air and the sound produced bu this is heard at a distance of 175 m. Now if the body is vibrated in water, what is the difference in the time taken by the sound to travel the same distance in water and air ? (The velocity of sound in air and water is 350 ms^(-1) and 1400 ms^(-1) , respectively).
