The eye is actually a multiple-lens system, but we can approximate it with a single-lens system for most of our purposes. When t
he eye is focused on a distant object, the optical power of the equivalent single lens is 45.4 diopters. a. What is the effective focal length of the eye?Feff = ____________ cmb. How far in front of the retima is this "equivalent lens" located?di= ______________ cm
For an object to be in equilibrium, it must be experiencing no acceleration. This means that both the net force and the net torque on the object must be zero.
