Part A How far from a 30.0 −mm -focal-length lens must an object be placed if its image is to be magnified 3.00 × and be real? Part B What if the image is to be virtual and magnified 3.00×?
How far from −56.0-mm-focal-length lens must an object be placed if its image is to be magnified 2.50× and be real? Follow the sign conventions. [Hint: Consider real objects and virtual objects (formed by some other piece of optics).]
A spherical lens with a focal length of 75 cm is sitting 30 cm to the left of a spherical mirror that has a focal length of −200 cm. A candle is then placed to the left of the lens so that the focal point of the lens is midway between the object and its vertex. (a) Find the object and image distance for the mirror. p2 = ?cm q2 = ?cm (b) Describe the image produced by the mirror....
