The schematic illustrates the cornea–lens system of the eye forming an image on the retina. Given that d = 1.7 cm, p = 8.0 m, and the object height is [ho] m, determine the height of the image formed on the retina (unit in mm).

 A slide projector needs to create a 98-cm-high image of a 2.0-cm-tall slide. The screen is [d] cm from the slide. What focal length does the lens need (unit in cm)? Assume that it is a thin lens. [Hint: the image is real or virtual?]

The schematic illustrates the far point and near point of the eye. Given that q = [q] cm, p = 25 cm, and d = 1.7 cm, determine the refractive power (in diopters) of a corrective lens required so that objects at infinite distance can be seen clearly.
