Draw a ray diagram to show that a convex mirror has a wider field of view.

उत्तर
In the case of a convex mirror, all rays incident parallel to the principal axis appears to diverge from a Focal point. So it has a wider field of view as it converges all rays to a single point.

A 4 cm tall object is placed on the principal axis of a convex lens. The distance of the object from the optical centre of the lens is 12 cm and its sharp image is formed at a distance of 24 cm from it on a screen on the other side of the lens. If the object is now moved a little away from the lens, in which way (towards the lens or away from the lens) will he have to move the screen to get a sharp image of the object on it again? How will the magnification of the image be affected?
