A simple microscope consists of two lenses as shown at below. The object is just placed outside of the focal length of an objective lens with f = 5.00 mm (5.00 × 10−3 m). The focal length of the eyepiece is f=30.0mm (3.00 × 10−2 m). The microscope is being used to image a dust mite with a size of 0.30 mm. A. What is the angular size of the dust mite when observed with the naked eye at 0.30...

The focal lengths of the objective and the eyepiece in a microscope are 0.25 cm and 1.0 cm, respectively. An object is placed at 0.30 cm from the objective lens and the image of this object is viewed with the eyepiece adjusted for minimum eyestrain. The near-point distance of the person using the microscope is 25.0 cm. What is the final magnification of the microscope?
