Question

Explain why, if we strike a steel tumbler with a metal spoon lightly, we hear a feeble sound but if we hit the tumbler hard, a loud sound is heard.

Answer 1

this is because due to unplesant sound

Answer 2

Metal tumbler and spoon:

• When spoon strikes tumbler, it produces vibration in tumbler.
• The quantity of sound heard is called as loudness. The vibration has amplitude of the sound.
• Loudness of the sound is proportional to square of amplitude of the vibration.
• So, when the vibration is weak, then the loudness is less and when the vibration is more, then the loudness is high.
• Loudness solely depends on amplitude and it is expressed with unit called decibel.
