Answer the following in brief:
The time interval between the original sound and its reflected sound in a room is \(0.05\ s\). Determine whether this results in an echo or reverberation. Give a suitable justification.
The reflected sound reaches the ear \(0.05\ s\) after the original sound. For a distinct echo to be heard, the reflected sound should reach the ear after a minimum time interval of about .
Since , the reflected sound will not be heard as a separate sound. Instead, it will merge with the original sound and .
Therefore, the sound will produce .
