You will explore some of the differences between real and paraxial rays in this
problem. For each part below, trace the specified ray and determine where it
crosses the optical axis. Show all calculations and include a diagram. Report your
answers to 4 decimal places.
(a)
Find L when
θ
= 5° with real ray (no paraxial approximation).
(b)
Find L when
θ
= 0.5° with real ray (no paraxial approximation).
(c)
Report part (a) with the paraxial ray (paraxial approximation).
(d)
Report part (b) with the paraxial ray (paraxial approximation).
(e)
Is there a difference between your answers in (a) and (b)? Is there any
difference between your answers in (c) and (d)?
(f)
Now compare your answers in (b) and either (c) or (d). Why are they so
similar?
