PhysicsLAB: 2008 Form B

A thin converging lens L of focal length 10.0 cm is used as a simple magnifier to examine an object O that is placed 6.0 cm from the lens.

	(a) On the figure below, draw a ray diagram showing at least two incident rays and the position and size of the image formed.

	(b) Indicate whether the image is real or virtual. Justify your answer.

	(c) Calculate the distance of the image from the center of the lens. (Do NOT simply measure your ray diagram.)

The object is now moved 3.0 cm to the right, as shown below.

	(e) Is the height of the new image larger, smaller, or the same size as the previous image? Justify your answer.
