1. The problem statement, all variables and given/known data I've tried to attached the image of the diagram. If that isnt working please let me know. Height of incident marginal ray now 25. Assume a thin lens. Find: a. the effective focal length b. the power of the lens c. surface curvature for front and back surfaces (assume equiconvex shape) d. radius of curvature for each surface e. format size (assume square) f. Airy disk diameter 2. Relevant equations a. the effective focal length 1/f=1/u+1/v F=1/2*r b. the power of the lens p=1/f c. surface curvature for front and back surfaces (assume equiconvex shape) C=1/R d. radius of curvature for each surface F=1/2*r e. format size(assume square) f. Airy disk diameter =2.44*λ*f ⁄# 3. The attempt at a solution With the known formulas I dont think I have enough information to solve anything besides f. and the solution to part f doesn't help solve the other parts. If I can just find the focal length I think the rest will fall into place.Can you point me towards whatever bit of information I'm missing? Thanks so much.
