Magnification of the microscope

Description

Optical magnification is the ratio between the apparent size of an object (or its size in an image) and its true size, and thus it is a dimensionless number.
A microscope makes a small object appear as a much larger object at a comfortable distance for viewing. A microscope is similar in layout to a telescope except that the object being viewed is close to the objective, which is usually much smaller than the eyepiece.
An eyepiece, or ocular lens, is the lens that is closest to the eye when someone looks through the device. The objective lens or mirror collects light and brings it to focus creating an image. The eyepiece is placed near the focal point of the objective to magnify this image.
The angular magnification of the microscope is related to the magnification of the objective and the magnification of the eyepiece.
