Question

Which of the following is the speed of sound in water and which in steel?
(a) 5000 m/s
(b) 1500 m/s
(c) 340 m/s

Answer 1

Answer:

b) 1500m/s is speed of sound in water.... (approx) .speed is less than 1500m/s

a) speed of sound in steel is 5000m/s (approx). it is much greater than 5000m/s

Answer 2

Water - 1500 m/s

Steel - 5000 m/s

Explanation:

Sound travels about 5 times faster in water than in air. Sound can be heard very fast inside water. This principle is used by creatures like dolphins and whales living in the sea water to communicate with one another. Sound travels at a speed of 5000 meters per second through iron or steel. Sound travels faster through a solid compared to a liquid.  

Speed of sound:

Water - 1500 m/s

Air - 240 m/s

Iron/steel - 5000 m/s
