(a) Draw a labelled diagram showing how a plane mirror forms an image of a point object placed in front of it.

(b) State the characteristics of the image formed in a plane mirror.

(a) An extended object in the form of an arrow pointing upward has been placed in front of a plane mirror. Draw a labelled ray-diagram to show the formation of its image. (b) State the uses of plane mirrors.

An object is placed at a distance equal to 2f in front of a convex lens. Draw a labelled ray diagram to show the formation of image. State two characteristics of the image formed.

(a) Draw a labelled ray diagram to show the formation of image of an object by a convex mirror. Mark clearly the pole, focus and centre of curvature on the diagram. (b) What happens to the image when the object is moved away from the mirror gradually ? (c) State three characteristics of the image formed by a convex mirror.

Draw a ray diagram to show the formation of image of an object kept in front of a convex mirror. State three characteristics of the image.

An object is placed at a distance of 10 cm from a convex mirror of focal length 5 cm. (i) Draw a ray-diagram showing the formation of image. (ii) State two characteristics of the image formed. (iii) Calculate the distance of the image from mirror.
