Subjective Type

(a) Draw a labelled ray diagram to show the formation of image in a convex mirror when the object is at infinity. Mark clearly the pole and focus of the mirror in the diagram. (b) State three characteristics of the image formed in this case. (c) Draw diagram to show how a convex mirror can be used to give a large field of view.

Solution

b. i.When the object is moved away from the mirror, then the size of the image goes on decreasing.

ii. Image formed by a convex mirror is virtual, erect and diminished.

iii.A convex mirror to give a large field of view.
