hi, i am Drishya.i am a little bit confused with a question based on the reflection of sound.it is said that if an object is 17 m or more away from the source of sound we can hear the echo.but my question is 'when we put a drinking glass close to our mouth such that it covers our mouth and we make a sound it will be heard reflected even if it is not 17m awy from the source of sound.how does this happen?'

Answer:
Dear student
When you place your mouth close to the glass and make a sound; the reflected sound you hear is not due to echo but due to 'reverberation'; sometimes in empty rooms also you can experience reverberation.
For echo to take place the minimum distance between the source of sound and listener should be 17m.
Hope this helps.
