Variables are set to proper values at entry. Note, value of unknown should be set to 0.0. Enter any 5 of 6 knowns, program calculates missing (=0) one. (a) R1=1e6, R2=-4, S[I]=10. (b) R1=4, R2=1e6, S[I]=10. Designate a plane with R=large number.||A source is 20 cm from a glass (ng=1.6) convex-plano lens with a radius of curvature of 4 cm. Where is the image located (a) when its flat surface faces source and (b) when its flat surface is away from source? Type comma key to see answer. Type (F2) to return to application file."
