Question

Take a matellic tumbler and a tablespoon. Strike the tablespoon gently at the brim of tumbler. Hear the sound produced. Now bang

the spoon on the tumbler and hear
the sound produced again. Is the
sound louder when the tumbler is
struck hard?
Now suspend a small thermocole
ball touching the rim of the tumbler
(Fig. 13.17). Vibrate the tumbler by
striking it. See how far the ball is
displaced. The displacement of the
ball is a measure of the amplitude
of vibration of the tumbler.
Now, strike the tumbler gently
and then with some force. Compare
the amplitudes of vibrations of the
tumbler in the two cases. In which
case is the amplitude larger?​
