How is magnification calculated using simple micrroscope?
Total magnification is determined by multiplying the magnification of the ocular lens by that of the objective lens. Compound microscope that uses more than one lens to direct light through a specimen mounted on a glass slide.

magnification.
The magnification of a telescope is changed by changing the what?
The magnification of a telescope is the ratio of the effective focal length of the objective to the focal length of the eyepiece. For example, a small telescope's objective may have a focal length of 800mm. When an eyepiece with a focal length of 25mm is used, the magnification is 800/25 = 32. The term "effective focal length" refers to the focal length of the objective as affected by any "focal extender". Many telescopes are designed to have a short total size, but high power, by "folding" the optical path. A mirror-type objective with a focal length of perhaps 800mm is coupled with a smaller curved mirror that intercepts the last 200mm and extends it to 800mm, a 4x extension, so that the effective focal length of that objective is 3200mm. Use that with a 25mm eyepiece and the magnification is 3200/25 = 128. By the way, if a telescope is smaller than you are, it is seldom much use to view using a magnification greater than 50 to 100. Most objects are best viewed at relatively low powers such as 30 or so.
Why do you use on or slide to be examined with the oil immersion objective?
If you are using the oil immersion objective on a microscope, you must use oil to increase the resolution of the lens. These lens are used at very high magnification.
What is the lens that is closest to the eye in a light microscope?
On a microscope with the usual 3-lens turret it is usual to use the objective lens with the lowest magnification to first examine your specimen. This gives a wider overall view of the subject, and will allow you to choose the particular detail that best suits your study. You may then move on to a higher magnification, if necessary, to study finer detail. If you started with the highest magnification, your fine focus will be uncertain, and you risk the front of the objective lens coming into contact with the sample slide. This could damage your specimen, and may damage the front of the lens.
Is total magnification an eyepiece magnification plus an objective magnification?
The total magnification is the object magnification for example 4x,10x etc. times eyepiece magnification usually 10x and you get the total magnification. The objective lens magnification is the lens right above the slide usually 4x,10x etc.

How does 4x on the low power equal 40 x on the microscope?
The objective lens (right above the slide stage) is 4x. The eyepiece (what you look into) is 10x. 4 times 10 = 40. Whatever the objective lens power is, you have to multiply it by the eyepiece power (usually 10x) to get the overall magnification.

magnification.
Would the ocular unit increase or decrease as magnification increases?
Field of view will decrease as the aperture remain same but things become larger and so we can see smaller area after magnification

Where are your eyes when changing the magnification?
You should be watching the objective lens move into place to make sure that it is not going to hit the slide.
What does the objective lens in a microscope do?
The objective lens in a microscope helps to magnify the object being viewed on the slide. The objective lens can be rotated to change the magnification of the lens and yield a different view.
