Find which pulse reaches the microphone first

Reference no: EM13488629

A hammer strikes one end of a thick iron rail of length 5.83 m. A microphone located at the opposite end of the rail detects two pulses of sound, one that travels through the air and a longitudinal wave that travels through the rail. (The speeds of sound in air and in iron are 343 m/s and 5950 m/s, respectively.)

(a) Which pulse reaches the microphone first?

the pulse traveling through the iron rail

the pulse traveling through the air

(b) Find the separation in time between the arrivals of the two pulses.
