    A string of length 2 m fixed between two supports vibrates in two loops. The distance between node and antinode is -

    A) 50 cm              

    B) 10 cm

    C) 100 cm             

    D) 200 cm

    Correct Answer: A

    Solution :

    \[\because \,\,\,\,\,\,\,\frac{\lambda }{2}=1\] \[\therefore ~~~~~~\lambda =2\text{ }metre\] \[\therefore \] Distance between nearest node and antinode is \[\frac{\lambda }{4}=\frac{2}{4}=\frac{1}{2}\,\,m\,\,=\,\,50\,\,cm\]
