A teacher is examining laboratory supplies with a diverging lens. The lens has a focal length of magnitude 18.4 cm. The lens is always held between the teacher's eye and the object under study. However, the distance between the lens and the object is different for each object that the teacher observes. Determine the image location and magnification for each of the following three objects. In addition, determine whether the image is real or virtual, whether it is upright or...

Build a microscope that can double the size of an object. We need to choose two converging lenses from these available lenses with focal lengths 2,4,8, and 12 meters. First choose an objective lens focal length, and a distance to place the object from the lens. Then choose an eyepiece lens focal length and a distance to place the lens from the objective lens. Draw your microscope design including a ray diagram. Your diagram should include: 1. Location and properties...
