A positive lens has a focal length of 15 cm. An object is located 36 cm from the lens. a) How far from the lens is the image? b) Is the image real or virtual, upright or inverted? c) Trace three rays from the top of the object to confirm your results.

A 6.25 mm high firefly sits on the axis of, and 12.9 cm in front of, the thin lens A, whose focal length is 6.79 cm. Behind lens A there is another thin lens, lens B, with a focal length of 23.9 cm. The two lenses share a common axis and are 56.3 cm apart. a) Is the image of the firefly that lens B forms real or virtual?. b) How far from lens B is this image located? Express the answer as a positive number. c) What is the height of this image? Express the answer as a positive number. d) Is this image upright or inverted with respect to the firefly?

In the following three scenarios, an object is located on one side of a converging lens. In each case, you must determine if the lens forms an image of this object. If it does, you also must determine the following. whether the image is real or virtual whether the image is upright or inverted the image's location, q the image's magnification, M The focal length is  f = 60.0 cm  for this lens. Set both q and M to zero if no image exists. Note: If q appears to be infinite, the image does not exist (but nevertheless set q to 0 when entering your answers to that particular scenario). (a) The object lies at position 60.0 cm. (Enter the value for q in cm.) q= cmM= Select all that apply to part (a).  realvirtualuprightinvertedno image (b) The object lies at position 7.06 cm.

Two thin lenses with focal lengths of magnitude 15.0 cm, the first diverging and the second converging, are placed 12.00 cm apart. An object 3.00 mm tall is placed 5.50 cm to the left of the first (diverging) lens. Where is the image formed by the first lens located? Please provide a detailed explanation of the process. How far from the object is the final image formed? Please describe the steps taken to reach to your conclusion.
