In one metre long open pipe what is the harmonic of resonance obtained with a tuning fork of frequency 480 Hz?

An organ pipe open at one end is vibrating in first overtone and is in resonance with another pipe open at both ends and vibrating in third harmonic. The ratio of length of two pipes is

In a resonance pipe the first and second resonances are obtained at depths 22.7 cm and 70.2 cm respectively. What will be the end correction?

An open tube is in resonance with string (frequency of vibration of tube is n₀). If tube is dipped in water so that 75% of length of tube is inside water, then the ratio of the frequency of tube to string now will be

Two closed organ pipes A and B, have the same length. A is wider than B. They resonate in the fundamental mode at frequencies n_A and n_B respectively, then

In a closed organ pipe, the 1st resonance occurs at 50 cm. At what length of pipe, the 2nd resonance will occur?

If in a resonance tube a oil of density higher than that of water is used then the resonance frequency would be

The frequency of the fundamental note in an organ pipe is 240 Hz. On blowing air, frequencies 720 Hz and 1200 Hz are heard. This indicates that organ pipe is

If L₁ and L₂ are the lengths of the first and second resonating air columns in a resonance tube, then the wavelength of the note produced is

A hollow cylinder with both sides open generates a frequency f in air. When the cylinder vertically immersed into water by half its length the frequency will be
