WebThe thin lens focal length would be f = m = cm. A thick lens of thickness d = cm = m would have effective power given by Gullstrand's equation: P thick lens = m -1 The equivalent focal length for the thick lens would be f equiv = m = cm. For the thin lens, we can calculate the image distance. For object distance o = m, the image distance is i = m.
