    A plane mirror reflecting a ray of incident light, is rotated through an angle 6 about an axis through the point of incidence in the plane of the mirror perpendicular to the plane of incidence. Then the reflected ray will rotate through an angle equal to:

    A)  \[3\theta \]              

    B)  \[2\theta \]

    C)  \[\theta \]                

    D)  \[0.8\theta \]

    Correct Answer: B

    Solution :

     The angle of incidence ray in the normal plane is equal to the angle of reflection. Hence, the total angle between incident and reflected ray is\[2\theta \].
