A student microscope has a 10× objective and a 15× eyepiece. A student is using the microscope to view a thin slice of an apple. The cells in the apple have a diameter of 0.10 mm. Assume a length L = 160 mm.

part a:

How far from the objective lens should the apple slice be placed?

part b:

Determine the angular size of a cell when viewed through the microscope.

part c:

Determine the angular size of a 19-mm-diameterpenny at a distance of 25 cm.

A microscope has an objective lens with a focal length of 16.22 mm and an eyepiece with a focal length of 9.28 mm. With the length of the barrel set at 31.0 cm, the diameter of a red blood cell's image subtends an angle of 1.43 mrad with the eye. If the final image distance is 31.0 cm from the eyepiece, what is the actual diameter of the red blood cell?

The distance between the eyepiece and the objective lens in a certain compound microscope is 21.4 cm. The focal length of the objective is 0.480 cm, and that of the eyepiece is 1.50 cm. Find the overall magnification of the microscope. (The near point of the eye is 25 cm. Assume that the object is placed at the focal point of the objective lens, and one places the eyepiece at the near point of the eye.)
