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 placed 5cm in front of a diverging lens of focal length 25 cm. A second converging lens of focal length 15cm is positioned 20 cm to the right of the first lens. What is the final image distance? What is the magnification of the final image? Is it upright of inverted? Real or virtual?

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...

1) The distance from the lens to the retina is 3.1 cm, what is the effective focal length of the lens when staring at an object infinitely far away? 2) An object is moved to 40cm from the eye. What must the focal length of the eye be to focus the image on the retina? 3) In the near sighted eye, images focus before hitting the retina. Suppose the focal length of the lens is 1.9 cm, while the distance...

2. Correcting vision: quantitative. Corrective lenses work because the lens bends light such that it, combined with the eye itself, light forms a clear image on the retina. Another way to think about this is that the corrective lens (glasses) form an image of the object at a location where the eye can see clearly without corrective lenses. For a nearsighted person viewing an object very far away (object at infinity), the lens corrective lens creates an image at the...
