The town hall building is situated close to Boojho’s house. There is a clock on the top of the town hall building which rings the bell every hour. Boojho has noticed that the sound of the clock appears to be much clearer at night. Explain.

Boojho has noticed that the sound of the clock appears to be much clearer at night because:

⇒ During the day, there are number of vibrations travel in the surroundings.

⇒ So the sound coming from the alarm gets distracted and amplitude of vibrations becomes small.

⇒ As a result, the loudness of sound become slow.

⇒ During the night, the noise level is quite low. There are no multiple vibrations travel in the surroundings.

⇒ Thus, the sound becomes clear and loud.
