ICSE Class 10 Physics 2022 Solved Paper

The diagram below shows a vibrating tuning fork E mounted on a sound box X. When the vibrating tuning forks A, B, C and D are placed on the sound box Y one by one, it is observed that a louder sound is produced when the tuning fork B is placed on Y.

Question : 35

Total: 45

Why does B produce a louder sound?

Solution:

B produce a louder sound as it is in resonance with tuning fork E. The frequency of B matches with the natural frequency of E and due to resonance the amplitude of vibration increases thereby increasing the loudness.
