A microbiologist uses a simple magnifying lens with a focal length of 5.0 mm to view an organism 0.439 mm long. Viewed through the magnifier with a relaxed eye, what is the angular size of the organism as seen by the microbiologist, in radians? Hint: Where is the organism placed with respect to the lens?
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.
