Question

A man is cutting down a tree with an axe. He hears the echo of the impact of the axe hitting the tree after 1.6 seconds.
(i) what sort of obstacle could have caused this echo

Answer 1

The sound may have encountered a mountain nearby.

Answer 2

The obstacle should be big and far enough to produce an echo. One such possibility is the presence of a mountain or a hill, or maybe a huge building.


Hope it helps :)
