  • Question 1/10
    4 / -1
    A closed organ pipe and an open organ pipe are tuned to the same fundamental frequency. What is the ratio of lengths?
    Solutions

  • Question 2/10
    4 / -1
    Find the fundamental frequency of closed pipe, if the length of the air column is 42 m. (speed of sound in air = 332 m/sec)
    Solutions

  • Question 3/10
    4 / -1
    The frequency of fundamental tone in an open organ pipe of length 0.48 m is 320 Hz. Speed of sound is 320 m/sec. Frequency of fundamental tone in closed organ pipe will be
    Solutions

  • Question 4/10
    4 / -1

    Solutions

  • Question 5/10
    4 / -1
    Two open organ pipes of length 25 cm and 25.5 cm produce 10 beat/sec. The velocity of sound will be
    Solutions

  • Question 6/10
    4 / -1
    What is minimum length of a tube, open at both ends, that resonates with tuning fork of frequency 350 Hz? [velocity of sound in air = 350 m/s]
    Solutions

  • Question 7/10
    4 / -1
    Two open organ pipes give 4 beats/sec when sounded together in their fundamental nodes. If the length of the pipe are 100 cm and 102.5 cm respectively, then the velocity of sound is
    Solutions

  • Question 8/10
    4 / -1
    An open pipe is suddenly closed at one end with the result that the frequency of third harmonic of the closed pipe is found to be higher by 100 Hz, then the fundamental frequency of open pipe is
    Solutions

  • Question 9/10
    4 / -1
    Tube A has both ends open while tube B has one end closed, otherwise they are identical. The ratio of fundamental frequency of tube A and B is
    Solutions

  • Question 10/10
    4 / -1
