AIPMT PRELIMS 2001 Physics Sonometer MCQ Question

Type: MCQ-conceptual-Medium-Class 11

If the tension and diameter of a sonometer wire of fundamental frequency n is doubled and density is halved then its fundamental frequency will become

A

n/4

B

√2 n

C

n

D

n/√2

Correct Answer

Option C

Detailed Explanation

The fundamental frequency of a sonometer wire is given by n = (1/2L)√(T/μ). If tension T is doubled and density is halved, the frequency becomes √2 times the original frequency.
