Question

A microscope has a low-power magnification of 200x and a high-power
magnification of 1600x. If the low-power field diameter is 1.2 mm, calculate the
high-power field diameter in micrometres (um). Show your work.Please do it step by step​

Answer 1

Answer:

For a microscope:

diameter of field of View (doFOV) x magnification (mx) = Constant

=>(doFOV) #1 x (mx) #1 = (doFOV) #2 x (mx) #2

=>1.2 x 10^-3 x 200 = (doFOV) #2 x 1600

=>(doFOV) #2 = 150 x 10^-6 OR 150 μm

Answer 2

Answer:

A compound microscope has two sets of lenses. The lens you look  through is called the ocular. The lens near the specimen being examined is called the objective. The objective lens is one of three or four lenses located on a rotating turret above the stage, and that vary in magnifying power. The lowest power is called the low power objective (LP), and the highest power is the high power objective (HP). 

 

You can determine the magnifying power of the combination of the two lenses by multiplying the magnifying power of the ocular by the magnifying power of the objective that you are using. For example, if the magnifying power of the ocular is 10 (written 10X) and the magnifying power of an objective is 4 (4X), the magnifying power of that lens combination is 40X
