Ray Tracing with Lenses and Mirror
Ray tracing is one experiment where you get to see how the physics of light (aka optics) behaves when it
interacts with lenses and a mirror. (All questions are in the lab manual.)
Part I: Lenses
Exercise 1: Focal Length of a Converging Lens
fC =
Exercise 2: Focal Length of a Diverging Lens
fD =
Exercise 3a: Focal Length of a Combination of Lenses
(fC – d) =
Precision of Combination of Lenses
f%
=
Question 1:
Exercise 4: Real Image from a Combination of Lenses
PMEAS =
PCALC = (use the lens formula twice in a row – once for the first lens to find its object and then again to
determine the final location, P, of the image from the second lens. NOTE: Delete this hint before you
print this lab report form.)
P% = 100 * (PMEAS - PCALC)/PMEAS =
Part II: Concave Mirror and Lenses
