A glass lens with radii R1=+3.0cm and R2=+3.0cm has an index of 1.60 and a thickness of 3.0cm. It is placed in the end of a tank so that air is in contact with face R1, and a transparent oil of index 1.30 is in contact with face R2.
a) Find the primary and secondary focal lengths.
b) Determine the powe of the system as a lens.
c) Calculate the primary and secondary focal points.
d) Calculate the primary and secondary principle points.
