Abstract

In optics class we often derive refraction at spherical surfaces (which is

ultimately the same as for cylindrical surfaces). We then move on to apply

the thin lens approximation and come up with the thin lens equation.

However, students generally are unwilling to apply the expressions we have

derived in general situations, preferring to misapply the convenient thin

lens equation and lens makers equation. For this reason we provided the

students with an investigation in which the students were required to use

the more general expressions for curved refracting surfaces. The investigation

and results will be presented.
