Question

Are reverberation and echo is similar?

Answer 1

Echo and reverberation is basically same thing but there are some differences between reverberation and echo:

Echo	Reverberation
An echo is basically a sound reflected from any surface. It is a single reflected sound wave.	Reverberation is basically the superposition of sound waves reflected from the different surfaces.
The echo is clear and distinguishable to hear.	Reverberation is not clear in maximum time. It is not clear and undistinguished to hear with respect to Echo.
Echo takes place within small small distance.	There is no particular range to occur reverberation.
