Question

Write any two differences between
i) Echo and Reverberation
ii) Intensity of sound and pitch of sound​

Answer 1

Answer:

a) 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. On the other hand, an echo occurs when a pulse of sound can be heard twice.

b) Intensity is the amount of energy a sound has over an area. Pitch, which depends on frequency, helps us distinguish between low and high sounds.
