  • Question 1/10
    4 / -1
    Stationary waves are set up in air column. Velocity of sound in air is 330 m/s and frequency is 165 Hz. Then distance between the nodes is
    Solutions

  • Question 2/10
    4 / -1
    An open pipe of length 1 vibrates in fundamental mode. The pressure variation is maximum at
  • Question 3/10
    4 / -1
    Fundamental frequency of an open pipe of length 0.5 m is equal to the frequency of the first overtone of a closed pipe of length l. The value of lc is (m)
    Solutions

  • Question 4/10
    4 / -1
    In a closed organ pipe the frequency of fundamental note is 50 Hz. The note of which of the following frequencies will not be emitted by it?
  • Question 5/10
    4 / -1
    On producing the waves of frequency 1000 Hz in a Kundt\'s tube, the total distance between 6 successive nodes is 85 cm. Speed of sound in the gas filled in the tube is
    Solutions

  • Question 6/10
    4 / -1
    What is the base frequency if a pipe gives notes of frequencies 425, 255 and 595 and decide whether it is closed at one end or open at both ends?
    Solutions

  • Question 7/10
    4 / -1
    A student determines the velocity of sound with the help of a closed organ pipe. If the observed length for fundamental frequency is 24.7 m, the length for third harmonic will be
    Solutions

  • Question 8/10
    4 / -1
    In open organ pipe, if fundamental frequency is n then the other frequencies are
  • Question 9/10
    4 / -1
    If in an experiment for determination of velocity of sound by resonance tube method using a tuning fork of 512 Hz, first resonance was observed at 30.7 cm and second was obtained at 63.2 cm, then maximum possible error in velocity of sound is (consider actual speed of sound in air is 332 m/s)
    Solutions

  • Question 10/10
    4 / -1
    An organ pipe, open from both end produces 5 beats per second when vibrated with a source of frequency 200 Hz. The second harmonic of the same pipes produces 10 beats per second with a source of frequency 420 Hz. The frequency of source is
