MHT CET Physics question
A tuning fork of frequency 340 Hz is held vibrating at the open end of an empty measuring cylinder of length 100 cm. Water is then poured in it slowly. What is the minimum height of water in cylinder, for which resonance will be obtained? Velocity of sound in air = 340 m/s, Neglect end correction. [MHT-CET 2022]
Answer: (A)
Solution
m, so the air column resonates at lengths cm and cm; the water height required for the
