- An open organ pipe has fundamental frequency 100 Hz. What frequency will be produced, if its one end is closed?
- A pipe closed at one end and open at the other end, resonates with sound waves of frequency 135 Hz and also 165 Hz, but not with...
- A glass tube is open at both the ends. A tuning fork of frequency f resonates with the air column inside the tube. Now, the tube...
- A cylindrical tube, open at both ends emits a fundamental frequency f in air. The tube is dipped vertically in water, so that...
- The end correction of a resonance column is 1.0 cm. If the shortest length resonating with the tuning fork is 15.0 cm, the next...
- A closed organ pipe of length 20 cm is sounded with tuning fork in resonance. What is the frequency of tuning fork? (Take, V=332...
- An organ pipe open at one end is vibrating in first overtone and is in resonance with another pipe open at both ends and...
- In a resonance column, first and second resonance are obtained at depths 22.7 cm and 70.2 cm. The third resonance will be...
- In 1 m long open pipe, what is the harmonic of resonance obtained with a tuning fork of frequency 480 Hz?
- Two instruments having stretched strings are being played in unison. When the tension of one of the instruments is increased by...

- Two closed organ pipes 100 cm and 101 cm long gives 16 beats in 20 s, when each pipe is sounded in its fundamental mode....
- Number of beats between A and B is 5 and between B and C is 3. Number of beats between A and C may be
- Beats are produced when two progressive waves of frequency 256 Hz and 260 Hz superpose. Then the resultant amplitude changes...
- When two harmonic sound waves of close (but not equal) frequencies are heard at the same time, we hear
