Echo occurs when a pulse of sound can be heard twice.
Reverberation is the persistence of sound after the sound source has been stopped. It results from a large number of reflected waves which can be perceived by the brain as a continuous sound.

Half knowledge is dangerous bro.. You are not able to explain why the distance should be 17 m.. You showed the calculation of distance 34 m but why the distance should be 17 m.. So, my suggestion is at first you get yourself a clear concept then think about making videos and explaining it to others. Just making videos won't help you to get viewers on youtube if you're not able to explain the topics properly. So please learn at first then teach others.
