Where on the axis of a converging lens, such as a biconvex lens, would you place an object in order to produce an image the same size as the original: put the object at twice the focal length from the lens. half way between the focal length and the center of curvature of the lens. between focal length and the lens. further away than the center of curvature. halfway between the center of curvature and the lens

SOLUTION SET UP The center of curvature of the first surface of the lens is on the outgoing side, so R = +6.0 mm. The center of curvature for the second surface is not on the outgoing side, so R2-_5.5 mn. We solve for f and then use the result in the thin-lens equation. Now we'll apply the thin-lens equation to the eye When light enters your eye, most of the focusing happens at the interface between the air and...

Chapter 35, Problem 37. The radius of curvature of the convex surface of a planoconvex lens is 68.4 cm. The lens is placed convex side down on a perfectly flat glass plate that is illuminated from above with red light having a wavelength of 580 nm. Find the diameter of the second bright ring in the interference pattern. Can you also please explain why you used the formulas in each step.
