STANDARD Physics Organ Pipes MCQ Question

Type: MCQ-numerical-Medium-Class 11

The two nearest harmonics of a tube closed at one end and open at other end are 220 Hz and 260 Hz. What is the fundamental frequency of the system?

A

20 Hz

B

30 Hz

C

40 Hz

D

10 Hz

Correct Answer

Option A

Detailed Explanation

Nearest harmonics of an organ pipe closed at one end differ by twice of its fundamental frequency. Therefore, 260220=2v260 - 220 = 2v, giving v=20v = 20 Hz.
