Question

2. Why do we keep frequency constant instead of keeping vibrating length constant to verify
second law of vibrating string?​

Answer 1

Answer:

Law of Mass: The fundamental frequency is inversely proportional to the square root of the mass per unit length. ... This verifies the law of length. Law of tension (f ∝ √T): The resonance of different tuning forks of different frequencies was observed by varying tension keeping resonating length and wire as constant
