    In the propagation of light waves, the angle between the direction of vibration and plane of polarisation is

    A)  \[{{0}^{o}}\]             

    B)  \[{{90}^{o}}\]

    C)  \[{{45}^{o}}\]

    D)  \[{{80}^{o}}\]

    Correct Answer: A

    Solution :

    Plane containing the direction of vibration and wave motion is called plane of polarisation. Plane of vibration is perpendicular to the direction of propagation and also perpendicular to the plane of polarisation. Therefore, angle between plane of polarisation and direction of propagation is 0°.
