1. Let's compare the image location for an eye filled with air to an eye filled with water. Do not fill the eye model with water yet. Put the +62 mm lens in Slot A near the cornea. Place the Pasco Basic Optics Light Source about 30 cm from the cornea of the eye model. The cross target on the front of the light source will be our object.

Take the white plastic retina screen and try to locate a position inside the eye model where a sharp image of the cross target is formed. Record this image distance. 4 cm

1. Question 2. Is the image on the retina a real or virtual image? Explain.
