1. By what angle mirror should be rotated to obtain reflected ray on +y-axis :
2. Assertion (A): Law of reflection is applicable for all type of mirrors. Reason (R): Rays which are parallel to principal axis are known as paraxial rays.  
3. Two plane mirrors A and B are aligned parallel to each other, as shown in the figure. A light ray is incident at an angle of 30° at a point just inside one end of A. The plane of incidence coincides with the plane of the figure. The maximum number of times the ray undergoes reflections (including the first one) before it emerges out is :
4. Assertion (A): Keeping a point object fixed, if a plane mirror is moved, the image will also move. Reason (R): In case of a plane mirror, distance of object and its image is equal from any point on the mirror.  
5. Assertion (A): The minimum length of mirror required to form complete image of man of height \(H) is \(H/2\). Reason (R): Image of an object is obtained if incident light ray reaches the reflecting surface.
