Medium power objective gives the medium (as oppose to large or small), field of
vision and the greatest depth of field. When you move the lens' position (CLose or far from the slide) it would be the middle.
Read the textbook it will be of more benefit; or look it up on the internet you are on anyways. Type [edu] with brackets for a page of more scholarly links (if their domain is .edu).
A) a long power objective- shortestB) a high power objective- longerC) a oil immersion objective- longest

Oil immersion is a technique used to increase the resolution of a microscope.

The Inverted microscope is mounted upside down, the light source and condenser are situated uppermost and direct light down through the stage. The objective is set with its front element uppermost, and the eyepieces are angled upward so that the observer can study specimens that are still in their watery medium.

You use the 3 objective lenses of a compound microscope to switch powers. There's LOW, MEDIUM, and HIGH power. With LOW power, you can magnify what you're looking at. With HIGH power, you can see things that you can't see with a naked eye.
That depends on which microscope you want to use. For a compound microscope, use the following steps:Place a slide with a coverslip on the microscope's stage.Turn on the light at the microscope's base, or turn the glass disc until you get light to the microscope.Choose the objective lens that you want to use to view your object.Use the coarse adjustment to focus in LOW and MEDIUM power.If you go to HIGH power, use the fine adjustment to focus.If you hold a microscope, hold the arm with one hand and hold the base with your other hand.

When working with a microscope you should always take procauctions but one question I am asked a lot is When working with a microscope do you open or close the diaphram when working with the medium- and high-power objective nobs? The answer is you keep it open if you don't you won't be abler to see any thing.
The power of a microscope magnification is the eye piece power times the objective lens so 10X eye piece times 10X objective is 100 power Common eyepieces are 10x 15x, 20X. The limit is about 2000X in an excellent unit. Average practical use is about 1000X to 1400X In expensive scopes the higher power objective lenes as 100X are made from oil not glass.
