When a steel pipe is hammered at one end,we hear two sounds at another end. Why?
(N/A) The sound produced by hammering travels through two different media to reach the other end of the pipe.
$1$. The first sound travels through the solid steel material of the pipe. Since the speed of sound in solids is significantly higher than in air,this sound reaches the listener first.
$2$. The second sound travels through the air present inside the hollow part of the pipe. Since the speed of sound in air is much lower,this sound reaches the listener later.
Because of the difference in the speed of sound in steel and air,we hear two distinct sounds.
