Can anyone help me with this? I do not quite understand how to do and what are the concepts behind this.
Qn
O-----------------------------------E < (Suggest that this is an 80m steel pipe with a large diameter and O and E are two ends of the pipe)
An eperimenter at E bangs the pipe and his assistant at O listens for the sound reaching him.
> Explain why the assistant will hear two sounds, one arriving before the other.
Reverberation? How? Why?
Thanks!
first sound travel through steel
2nd sound travel through air
reason because sound travels much faster in steel than air :D
Lol. I didn't know it was just like that. Thanks
