Draw suitable diagrams to illustrate the action of (i) concave mirror, and (ii) convex mirror, on a beam of light incident parallel to the principal axis.

Draw a concave mirror and a convex mirror and mark the reflecting surfaces on both.

Draw a diagram to illustrate the determination of the focal length of a convex lens using an auxiliary plane mirror.

Draw a diagram to show the reflection of a light ray incident normally on a plane mirror.

A point object 'O' is at the center of curvature of a concave mirror. The mirror starts to move at a speed u, in a direction perpendicular to the principal axis. Then, the initial velocity of the image is

By drawing a neat diagram show the formation of an image in a concave mirror when the object is between the pole and the principal focus of the mirror. State the characteristics of the image.

(a) Draw the ray diagram for the formation of image of an object by a convex mirror and use it (along with the sign convention) to derive the mirror formula. (b) Use the mirror formula to show that for an object, kept between the pole and focus of a concave mirror the image appears to be formed behind the mirror.

Draw a diagram showing the reflection of a light ray from a plane mirror. Label on it the incident ray, the reflected ray, the normal, the angle of incidence i and the angle of reflection r.

A converging lens and a diverging mirror are placed at a separation of 15 cm. The focal length of the lens is 25 cm and that of the mirror is 40 cm. Where should a point source be placed between the lens and the mirror so that the light, after getting reflected by the mirror and then getting transmitted by the lens, comes out parallel to the principal axis ?

(a) With the help of a suitable ray diagram, derive the mirror formula for a concave mirror.

Draw a diagram to show the reflection of a ray of light by a plane mirror. In the diagram, label the incident ray, the reflected ray, the normal, the angle of incidence and the angle of reflection.
