NEET 2014 Physics String Vibrations MCQ Question
Type: MCQ-conceptual-Medium-Class 11
If n₁, n₂ and n₃ are the fundamental frequencies of three segments into which a string is divided then the original fundamental frequency n of the string is given by
A
1/n = 1/n₁ + 1/n₂ + 1/n₃
B
1/√n = 1/√n₁ + 1/√n₂ + 1/√n₃
C
√n = √n₁ + √n₂ + √n₃
D
n = n₁ + n₂ + n₃
Correct Answer
Option A
Detailed Explanation
The fundamental frequency of the whole string is the reciprocal of the sum of the reciprocals of the frequencies of the segments.
