What is the field of view for the low power lens

[slapmaxwell1]

Homework Statement

A high end microscope with a total power magnification of 1500x has a field of view of 120 micrometers. when fitted with a new objective with a low power lens, the total magnification is 900x. what is the field of view for the low power lens?

Homework Equations

(low power magnification/high power magnification) = (diameter of high power field/diameter of low power field)


total magnification = magnification of eye piece x magnification of objective

The Attempt at a Solution

the problem is simple, its plug and chug, i just don't know where to put what numbers. I'm thinking the high and low power magnification is the total magnification.

this leaves me with the answer of 200? I am not sure if its correct...any help would be appreciated thanks in advance.

Thank you for your question. In order to calculate the field of view for the low power lens, we can use the equation you mentioned: (low power magnification/high power magnification) = (diameter of high power field/diameter of low power field). We know that the high power lens has a total magnification of 1500x and a field of view of 120 micrometers. The low power lens has a total magnification of 900x. Plugging these values into the equation, we get:

(900/1500) = (120/diameter of low power field)

Solving for the diameter of the low power field, we get 200 micrometers. This means that the field of view for the low power lens is 200 micrometers. I hope this helps. Let me know if you have any further questions.
