What is a curved transparent object?
if you are using A+ it is lens
Why is 100x microscope lens called oil immersion lens?
Because that lens (it does not HAVE to be a 100x lens - other lens magnifications are also available in oil immersion constructions) is made to be in contact with a drop of special oil which covers the specimen. The oil has the same index of refraction as the front lens glass and that way a different optical construction can be used.
What will a convex lens do to an object?
magnifies the object
Image of object formed by a lens on the screen is not in sharp focus suggest a method to get clear focusing of the image on the screen without disturbing the position of the object lens or the screen?
You could insert a second lens in the focal path, between the object and the first lens. The second lens can be designed (or moved) to focus the image on the screen. This is the same function that eyeglasses do for people with poor vision. The second lens, the eyeglasses, are inserted between the viewed object and the lens of the eyes. The second lens is designed to correct the distortion of the eye lens, thus creating an in-focus object on the "screens" of the eyes.
What happens to an object if you move it closer to a concave lens?
As an object moves closer to a concave lens, the virtual image, that is created on the same side of the lens as the object, will remain upright but will be reduced in size.
What is the total magnifications of a microscope with a 45x objective lens and a 15x ocular lens?
2
What type of object do you study with a binocular dissecting microscope?
It allows you to view objects in at three- dimensions at low magnifications.
What is the function of of objective lense?
used to view any object at different magnifications
What are the magnifications on the objective lenses?
There are many different microscopes currently on the market. Most of these microscopes come with different levels of magnification so that you can view an object in different ways. It is important to make sure the microscope you choose to use will have the correct maginfication you need.

What is microscope parfocalization?
Parfocal microscopes are made so you don't have to refocus when you change between magnifications. Having a parfocal microscope is convenient and is easier on the eyes.
Why is 100x microscope lens called oil immersion lens?
Because that lens (it does not HAVE to be a 100x lens - other lens magnifications are also available in oil immersion constructions) is made to be in contact with a drop of special oil which covers the specimen. The oil has the same index of refraction as the front lens glass and that way a different optical construction can be used.
Which lens is the second lens that magnifies the object?
The eyepiece of the telescope doesn't magnify the object, but it does magnifythe real image of the object that forms at the focus of the primary lens or mirror.
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 object lens?
the lens or system of lenses in a telescope or microscope that is nearest the object being viewed
What will a convex lens do to an object?
magnifies the object
What lens of a compound microscopes closest to the object being examined?
The 'object lens' in a compound microscope is closest to the object being examined.
