The speed of sound in air is 330 m`s^(-1)` and in water is 1650 m`s^(-1)`. It takes 2 s for sound to reach a certain distance from the source placed in air. How much time will it take for sound to reach the same distance when the source is in water ?

In water, V = 1650 m `s^(-1)` , d = 660 m `therefore ` Time taken by sound to travel the distance d in water will be `t= d/V = (660 m)/(1650 ms^(-1)) = 0.4 s`
The speed of sound in air is 330 m s^(-1) and in water is 1650 m s^(-1) . It takes 2 s for sound to reach a certain distance from the source placed in air. Find the distance.
Assuming the speed of sound in air equal to 340 m s^(-1) and in water equal to 1360 m s^(-1) , find the time taken to travel a distance 1700 m by sound in air .
Assuming the speed of sound in air equal to 340 m s^(-1) and in water equal to 1360 m s^(-1) , find the time taken to travel a distance 1700 m by sound in water.

The speed of sound in air is 332 in ms^-1. Is it advisable to define the length 1 m as the distance travelled by sound in 1/332 s ?
A source of sound emitting waves at 360 H_(Z) is placed in front of a vertical wall, at a distance 2 m from it. A detector is also placed in front of the wall at the same distance from it. Find the minimum distance between the source and the detestor for which the detector detects a maximum of sound. Take speed of sound in air = 360 m//s . Assume that there is not phase change in reflected wave.
