A sonometer wire is vibrating is resonance with a tuning frok. Keeping the tension applied same, the length of the wire is dourbled. Under what conditions would the tuning fork still be in resonance with the wire?

A sonometer wire resonates with a tuning fork. If the length of the wire between the bridges is made twice even then it can resonate with the same tuning fork. How ?

  • A sonometer wire vibrating in its fundamental mode, is in unison with a tuning fork when the length of the wire between the bridges is 25 cm. By keeping the same tension , the length between the bridges is increased to 75 cm. The tuning fork can still be in resonance with the vibrating wire , provided the wire vibrates with

    A
    2 loops
    B
    4 loops
    C
    5 loops
    D
    3 loops

  • A sonometer wire is in tnison with a tuning fork of frequency 256 Hz, when the lenghts of the wire between the bridges is 75 cm and only one loop is formed. By keeping the lengths and tension constant, the wire is made to vibrate with 2 loops. The wire can still be in resonance with a tuning fork, provided the freqency of the tuning fork is

    A
    100 Hz
    B
    512 Hz
    C
    384 Hz
    D
    128 Hz

  • A stretched sonometer wire is in unison with a tuning fork. When the length of the wire is decreased by 1% 6 beats/s are heard, then the frequency of the tuning fork is

    A
    594 Hz
    B
    606 Hz
    C
    600 Hz
    D
    612 Hz
