-
A.
diffraction
-
B.
resonance
-
C.
refraction
-
D.
reverberation
Correct Answer:
D. reverberation
Explanation:
The phenomenon where sound reflects multiple times off various surfaces in an enclosed space, causing the sound to persist even after the source has stopped, is known as reverberation. Each reflection arrives at the listener's ear at slightly different times, creating a continuous, lingering sound effect. This is distinct from a single echo, which is a discrete, delayed repetition of the original sound. Therefore, the repeated reflection that results in multiple echoes is specifically referred to as reverberation.
