An object 1.50 cm high is held 2.80 cm from a person's cornea, and its reflected image is measured to be 0.174 cm high.

(a)What is the magnification?

(b)Where is the image (in cm, from the corneal "mirror")

Find the radius of curvature (in cm) of the convex mirror formed by the cornea. (Note that this technique is used by optometrists to measure the curvature of the cornea for contact lens fitting. The instrument used is called a keratometer, or curve measurer.)

An object is placed 11.3 cm in front of the cornea. (The cornea is thin ans has approximately parallel sides so that the reflection that occurs as light travels from air to cornea to aqueous humor is essentially the same as though the aqueous humor were directly in contact with the air. The aqueous humor has index of refraction n = 1.34 and the radius of curvature of cornea is 7.8 mm.) (a) What is the image distance for the...
