Problem

The magnitudes of the radii of curvature for the spherical surfaces A and B are, respectively, |RA| = a and |R B| = 2a. The material of which the lens is made has an index of refraction n = 1.5. Find the focal length of the thin lens.

1. f = a

2. f = 2a

3. f = −2a

4. f = 4a

5. f = −3a

6. f = 3a

7. f = −a

8. f = −4a
