Two symmetric double convex lenses, a and b, have the same focal length, but the radii of curvature differ so that ra=0.9rb. If μa=1.63, then μb will be

Answer 1

Answer:

Two symmetric double convex lenses, a and b, have the same focal length, but the radii of curvature differ so that ra=0.9rb.

Answer 2

Explanation:

Hence measure of ûb will be ra=0.9rb. If μa=1.63,
