Question

In an experiment to measure the speed of sound in steel, a steel pipe of length 200 m is struck at one end with a hammer. A microphone at the other end of the pipe is connected to an accurate timer. The timer records a delay of 0.544 s between the arrival of the sound transmitted by the steel pipe and the sound transmitted by the air in the pipe.
The speed of sound in air is 343 m / s. Calculate the speed of sound in steel

Answer 1

Answer:

5128 m/s is the speed of sound in steel

Explanation:

we know that the...

steel pipe is 200 m

The speed of sound in air is 343 m / s

0.544 second delay

First, we have to find the time taken by sound in the air

sound = distance/time = 200m / 343 m/s= 0.583 s

Next, we have to find the time taken by sound in the steel

steel = time taken by sound - time taken by steel

=0.583 – 0.544 = 0.039s  

length of tube / time taken by steel

200m / 0.039s = 5128 m/s
