Questions from FOR DIFFERENT COMPETITIVE EXAMINATIONS with Hints & Solutions
A person blows into open-end of a long pipe. As a result, a high pressure pulse of air travels down the pipe. When this pulse reaches the other end of the pipe.
Standing waves can be produced:
One end of a taut string of length along the X-axis is fixed at . The speed of the waves in the string is The other end of the string is vibrating in the T-direction so that stationary Waves are set up in the string, the possible waveform (s) of these stationary waves is (are):
An air column in a closed pipe will be in resonance with a vibrating tuning fork of frequency 264 Hz, if the length of the column (in cm) is: ( the velocity of the sound in air is ).
A student is performing the experiment of Resonance Column. The diameter of the column tube is . The frequency of the tuning fork is The air temperature is in which the speed of sound is The zero of the meter scale coincides with the top of the resonance column tube. When the first resonance occurs, the reading of the water level in the column is
In the experiment to determine the speed of sound using a resonance column:
Select the correct alternative (s) :
A student performed the experiment to measure the speed of sound in air using resonance air- column method. Two resonances in the air-column were obtained by lowering the water level. The resonance with the shorter air-column is the first resonance and that with the longer air-column is the second resonance. Then :
Air is blown at the mouth of a tube (Length and diameter ) closed at one end. Velocity of sound is the sound which is produced will correspond to the frequencies :
