Examples : Open Area - Valley. Closed Area - Well. Can we deduce laws of echo ? Thanks & Regards, Prashant S Akerkar

The question is too general for a definite answer.

Depends...

Sound reflects from interfaces (i.e. a surface area between air and not-air). In a well, the walls are close together, so if an echo does occur, you'll notice it immediately. In a valley, there are also interfaces which can cause sound reflections, so if you have a very still atmosphere (i.e. no wind) you might hear echo as well, but it will be more delayed because the waves will have further to travel.

Yes... echos are just sound waves, so if you want to know how echoes work, you just need to learn about sound waves.

Open area : Valley,Mountain Closed area : Tunnel,Cave,Well Will Sound Reflected (Echo) be more in closed area than open area? How we can trace whether echo will be more in open or close area? Can we deduce laws of Echo similar to Newton's laws of motion? Thanks & Regards, Prashant S Akerkar
