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.
