A resonance tube closed at one end is of height 1.5m. A tuning fork of frequency 340 Hz is vibrating near the open end of the tube. Water is poured in the tube gradually. The minimum height of air column for which resonance is obtained is (neglect end correction, speed of sound in air = 340 m/s) - VgyanHub
