Q. What is the smallest diameter spot the eye can produce on the retina if the pupil diameter is 4.10 {rm mm}? Assume light with a wavelength of lambda = 600 {rm nm}. (Note: The distance from the pupil to the retina is 25.4 {rm mm}. In addition, the space between the pupil and the retina is filled with a fluid whose index of refraction is n = 1.336.

Q. A 2.50 syringe has an inner diameter of 4.00 , a needle inner diameter of 0.240 , and a plunger pad diameter (where you place your finger) of 1.2 cm. A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100.
