A*R*C*S 11.11.2. Human Eye.
The average human eye is about 2.4 cm in diameter, that is, the lens is 2.4 cm from the retina. Assume you have an average eye, and that an object that is 5.0 cm high is located 25 cm from your eye. What focal length must your lens be to create an image on your retina?
Tip: For your numerical sensemaking (part 3b): What type of lens is this? How can you tell?
