If the equation of mirror is given by then find the point on which horizontal ray should be incident so that the reflected ray become perpendicular to the incident ray



Important Questions on Ray Optics
A ray of light is incident normally on one face of prism of refractive index immersed in water of refractive index as shown in figure.

An object is kept inform of a converging lens of focal length behind which there is a plane mirror at from the lens.


Choose the correct alternative corresponding to the object distance '', image distance '' and the focal length '' of a converging lens from the following.
(i) The average speed of the image as the object moves with uniform speed from distance to is greater than the average speed of the image as the object moves with same speed from distance to




A ray is incident on the first prism at an angle of incidence as shown in the figure. The angle between side and for the net deviation by both the prism to be double of the deviation produced by the first prism, will be
