5. The angular magnification of a magnifyer is defined as the limit of the ratio of the tangent of the angle subtended by the image at the lens to the tangent of the angle subtended by the object at the eye (with the object at the eye's near point) as the object approaches the location of the focal point hy tan θ, Mlim (93) If the near point is taken to be 25 cm from the eye, what is the...
This is a two part question. Part 1. To look closely at a small object, such as an insect or a crystal, you bring it close to your eye, making the subtended angle and the retinal image as large as possible. But your eye cannot focus sharply on objects that are closer than the near point, so the angular size of an object is greatest when it is placed at the near point (25 cm away from a “normal” eye)....
The focal length of a simple magnifier is 8.50cm. Assume the magnifier to be a thin lens placed very close to the eye. How far in front of the magnifier should an object be placed if the image is formed at the observer's near point, 25.0cm in front of her eye? If the object is h=1.30 mm high, what is the height of its image formed by the magnifier?
A lens of focal length 40 mm is used as a magnifier. The object being viewed is 5.3 mm long, and is positioned at the focal point of the lens. The user of the magnifier has a near point at 25 cm. The angular magnification of the magnifier is closest to 5.

To view an enlarged upright image of an object through a simple magnifier, where must the object be located? Which choice is it below? (A) at the near point (B) at the focal point of the lens (C) within the focal length of the lens (D) between the near point and focal point (E) within the focal length of the lens, provided the focal length is shorter than the near point distance
