ICSE Class 10 Physics 2019 Solved Paper

It is observed that during march-past we hear a base drum distinctly from a distance compared to the side drums.

Question : 48

Total: 74

Give a reason for the above observation.

Solution:

The reason is that the length of the air column in the base drum is different as compared to the side drums. So the frequency of sound produced by the vibrations of their air column will be different (∵f∝‌

). Thus the pitch of sound will be different as pitch of sound depends on its frequency.
