A compound microscope has a total magnifying power of 200. If the objective produces a linear magnification of 25, the angular magnification of the eyepiece is:

Answer: 8.

A 8
B 5
C 10
D 4

Correct answer: A. 8

Explanation: Total magnification M = mo × me, so me = 200/25 = 8.

Concave mirror ray diagram with an object drawn as a candle on the principal axis, the focal point F marked, and the parallel ray and focal ray reflecting to form an inverted real image

Concave mirror ray construction: a ray parallel to the axis reflects through F, and a ray through F reflects parallel, locating the inverted real image. Image: Maxmath12, CC0, via Wikimedia Commons.

Concept context

Reflection, refraction, lenses, mirrors, total internal reflection.
