  • Question 1/10
    4 / -1
    Two uniform strings A and B made of steel are made to vibrate under the same tension, if the first overtone of A is equal to the second overtone of B and if the radius of A is twice that of B, the ratio of the lengths of the strings is
  • Question 2/10
    4 / -1
    If the length of a stretched string is shortened by 40% and the tension is increased by 44%, then the ratio of the final and initial fundamental frequencies is
  • Question 3/10
    4 / -1
    Two wires are fixed in a sonometer. Their tensions are in the ratio 8:1. The lengths are in the ratio 36:35. The diameters are in the ratio 4 : 1. Densities of the materials are in the ratio 1 : 2. If the lower frequency in the setting is 360 Hz. the beat frequency when the two wires are sounded together is
  • Question 4/10
    4 / -1
    A transverse sinusoidal wave moves along a string in the positive x-direction at a speed of 10 cm/s. The wavelength of the wave is 0.5 m and its amplitude is 10 cm. At a particular time t, the snap-shot of the wave is shown in figure. The velocity of point P when its displacement is 0.05

  • Question 5/10
    4 / -1
    A tuning fork of frequency 392 Hz, resonates with 50 cm length of a string under tension (T). If length of the string is decreased by 2%, keeping the tension constant, the number of beats heard when the string and the tuning fork made to vibrate simultaneously is
  • Question 6/10
    4 / -1
    The sound carried by air from a sitar to a listener is a wave of the following type
  • Question 7/10
    4 / -1
    In Melde\'s experiment in the transverse mode, the frequency of the tuning fork and the frequency of the waves in the strings are in the
  • Question 8/10
    4 / -1
    The frequency of transverse vibrations in a stretched string is 200 Hz. If the tension is increased four times and the length is reduced to one-fourth the original value, the frequency of vibration will be
  • Question 9/10
    4 / -1
    Two wires are producing fundamental notes of the same frequency. Change in which of the following factors of one wire will not produce beats between them?
  • Question 10/10
    4 / -1
    The fundamental frequency of a string stretched with a weight of 4 kg is 256 Hz. The weight required to produce its octave is
