Question 5(ii)

A linear object is placed on the axis of a lens. An image is formed by refraction in the lens. For all positions of the object on the axis of the lens, the positions of the image are always between the lens and the object.

(a) Name the lens.

(b) Draw a ray diagram to show the formation of the image of an object placed infront of the lens at any position of your choice except infinity.

Answer

(a) The lens is concave as the positions of the image are always between the lens and the object.
