What is the other function of the revolving nose piece?
The revolving nosepiece, sometimes called a "turret," contains 2 or 3 different objective lenses, each of a higher magnification. This enables the user to examine the object on the slide at different magnifications.
What type of lenses are used to enlarge an object?
Concave and convex lenses both enlarge an object to a certain extend.
How many times larger will an object appear if the microscope is set on the high power objective?
This depends entirely on the microscope you are using. Typical high lenses are 150x to 250x, some to 400x.
What holds the objective lenses on a microscope?
The slide hold the object being looked at.
What is the objective lens?
In an optical instrument, the objective is the optical element that gathers light from the object being observed and focuses the light rays to produce a real image. Objectives can be single lenses or mirrors, or combinations of several optical elements. They are used in microscopes, telescopes, cameras, slide projectors, CD players and many other optical instruments. Objectives are also called object lenses, object glasses, or objective glasses.
What is the advantage of the parfocal lenses?
The advantage of a parfocal microscope=when different objective lenses are rotated, the object being examined will remain in view
Has an objective lens that creates an image of the object which is enlarged by the eyepiece?
When needing to make something larger you will need a microscope. A microscope has two lenses; one being the objective lenses and the other is the ocular lens.
What is the function of thE REVOLVING?
It is to change the objective of the lenses in the microscope
Why is the objective lenss called the objective lenss on the microscope?
The objective lenses are the optical element that gathers light from the 'object' being observed and they focus the light rays to produce a real image.
How would changing the objective lenses affect what is seen through the microscope?
The object would be more clear or more blurry.

Why can't the objective lenses touch the slide?
If the objectives touch a slide, it will damage it, making it harder to observe the object you are viewing in the microscope.
What is a microscope lens placed directly above the specimen?
The microscope has two systems of lenses: the ocular lens into which the observer looks; and objective lenses placed directly above the object being observed.

What does an objective lens do to help a microscope function?
A simple microscope has two lenses. One the eye looks through and the objective lens nearest the object being observed. Changing the objective lens changes the magnification of the microscope, and can also change the amount of light on the object. The objective lens draws the light rays together to make a sharp image.
