Distinguish between an echo and a reverberation.
To explain: The difference between an echo and a reverberation.
Answer to Problem 10A
The echo is defined as the reflection of sound whereas the multiple reflections of sound are known as reverberation.
Explanation of Solution
Introduction:
As the light reflects when striking to the smooth surface, the sound also reflects.
When a sound reflects from a surface which is smooth, it follows the law of reflection which means that the angle of incidence is equal to the angle of reflection. The reflection of the sound is known as an echo. Sometimes when the sound is reflected many times,its process is known as reverberation. In reverberation, the sound becomes garbled. For example, if there is only one reflecting surface, then this is known as an echo but if there are multiple reflecting surfaces then this is known as reverberations.
Conclusion:
The echo is the single reflection of the sound whereas the reverberation is the multiple reflections of sound.
