A 1 m long tube of glass is in vertical position and is completely filled with water. Water leaks slowly from the bottom. If a vibrating tuning fork of frequency 495 be brought at the upper end of the tube, then at what positions of the water-level will the resonance occur at 0°C? The speed of sound at 0°C is 330 ms-1.

A pipe closed at one end is in resonance of a vibrating tuning fork when the length of the air column is 25 cm. The next resonance occurs when the length of the air column is 77 cm. If the speed of sound in air be 338 ms-1, then calculate the wavelength of the emitted note and the frequency of the fork.
