Speed of Sound

Which of the ...

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

Open in App

Solution

Speed of sound in air is 340 m/s at normal temperature and pressure. Speed of sound in denser mediums is higher than speed of sound in rarer mediums. Thus, speed of sound in water is higher than speed of sound in air and speed of sound in steel is higher than speed of sound in water. Therefore, we can infer and say
(a) Speed of sound in steel is 5000 m/s.

(b) Speed of sound in water is 1500 m/s.
