In Fig. 35-54, two isotropic point sources S 1 and S 2 emit light at wavelength λ = 400 nm. Source S 1 is located at y = 640 nm; source S 2 is located at y = –640 nm. At point P 1 (at x = 720 nm), the wave from S 2 arrives ahead of the wave from S 1 by a phase difference of 0.600 Π rad. (a) What multiple of λ gives the phase difference between the waves from the two sources as the waves arrive at point P 2 , which is located at y = 720 nm? (The figure is not drawn to scale.) (b) If the waves arrive at P 2 with equal amplitudes, is the interference there fully constructive, fully destructive, intermediate but closer to fully constructive, or intermediate but closer to fully destructive? Figure 35-54 Problem 90.

Express your answer in diopters to one decimal point.
Eye: A person with myopic eyes has a far point of 15 cm. What power contact lenses does she need to correct
her version to a standard far point at infinity? Give your answer in diopter to one decimal point.
Paraxial design of a field flattener. Imagine your optical system has Petzal curvature of the field with radius
p. In Module 1 of Course 1, a homework problem asked you to derive the paraxial focus shift along the axis
when a slab of glass was inserted in a converging cone of rays. Find or re-derive that result, then use it to
calculate the paraxial radius of curvature of a field flattener of refractive index n that will correct the observed
Petzval. Assume that the side of the flattener facing the image plane is plano. What is the required radius of
the plano-convex field flattener? (p written as rho )
