Which of the following best describes reverberation?
A single sound undergoes several reflections due to multiple reflecting surfaces.
O A fraction of the sound waves are absorbed by an object and converted to heat
energy.
A change in the sound wave velocity causes the wave to bend in a different
direction.
The wave fronts become mixed and broken up due to contact with a rough or
irregular surface.
