AIPMT PRELIMS 2000 Physics Harmonics MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A string is cut into three parts, having fundamental frequencies n₁, n₂ and n₃ respectively. Then original fundamental frequency 'n' related by the expression as :
A
1/n = 1/n₁ + 1/n₂ + 1/n₃
B
n = n₁ × n₂ × n₃
C
n = n₁ + n₂ + n₃
D
n = (n₁ + n₂ + n₃)/3
Correct Answer
Option A
Detailed Explanation
The original frequency is related to the frequencies of the parts by the reciprocal relationship due to the harmonic nature of the string.
