a) Can a diverging lens be used as a magnifier?

b) What is the maximum value that the focal length of a magnifying lens can have?

c) A magnifier has a magnification of 5X. How far from the lens should an object be held so that its image is at the near-point distance of 25 cm?

1. The focal lengths of the objective and the eyepiece of a microscope are 0.50 cm and 2.0 cm, respectively, and their separation adjusted for minimum eyestrain (with the final image at the viewer's far point) is 6.0 cm. The near point of the person using the microscope is 25 cm and the far point is infinity. a. If the microscope is focused on a small object, what is the distance between the object and the objective lens? b. If...

An object is a distance 15.6cm to the left of a diverging lens ("Lens 1") with a focal length of -19cm. Lens 1 is itself a distance 29cm to the left of a second diverging lens ("Lens 2") with a focal length -19cm. The object is along the optical axis of the two-lens system. How far is the image of the object due to Lens 2 away from Lens 2? Note that in this case the light has passed through...
