Q1. In an open organ pipe........wave is present

•  Transverse standing wave
•  Longitudinal standing wave
•  Longitudinal moving wave
•  Transverse moving wave

Q2. Two tuning forks have frequencies 450 Hz and 454 Hz respectively. On sounding these forks together, the time interval between successive maximum intensities will be

•  1/4 sec
•  1/2 sec
•  1 sec
•  2 sec

Q3. Two waves of lengths 50 cm and 51 cm produced 12 beats per second. The velocity of sound is

•  306 m/s
•  331 m/s
•  340 m/s
•  360 m/s

Q4. In stationary longitudinal waves, nodes are points of

•  Minimum pressure
•  Maximum pressure
•  Minimum pressure variation
•  Maximum pressure variation

Q5. A cylindrical tube, open at both ends, has a fundamental frequency f0 in air. The tube is dipped vertically into water such that half of its length is inside water. The fundamental frequency of the air column now is

•  3f0/4
•  f0
•  f0/2
•  2f0

Q6. A closed organ pipe and an open organ pipe are tuned to the same fundamental frequency. What is the ratio of lengths

•  1:2
•  2:1
•  2:3
•  4:3

Q7. An open pipe resonates with a tuning fork of frequency 500 Hz. it is observed that two successive nodes are formed at distances 16 and 46 cm from the open end. The speed of sound in air in the pipe is

•  230 m/s
•  300 m/s
•  320 m/s
•  360 m/s

Q8. In the experiment for the determination of the speed of sound in air using the resonance column method, the length of the air column that resonates in the fundamental mode, with a tuning fork is 0.1 m. when this length is changed to 0.35 m, the same tuning fork resonates with the first overtone. Calculate the end correction

•  0.012m
•  0.025m
•  0.05m
•  0.024m

Q9. Two sound sources when sounded simultaneously produce four beats in 0.25 second. the difference in their frequencies must be

•  4
•  8
•  16
•  1

Q10. At nodes in stationary waves

•  Change in pressure and density are maximum
•  Change in pressure and density are minimum
•  Strain is zero
•  Energy is minimum
