How is a simple microscope and a compound microscope different?
The difference lies in the number of lenses that each microscope has. A compound microscope has 2 or more lenses, like those found in most science classrooms. A simple microscope uses only 1 lens.
What is the function of the revolving nosepiece in the microscope?
The nose piece holds the odjective lense, rotates, and notes the positive stops for each lens.
What are the magnifying parts in a microscope?
The Magnifying Parts of the Microscope are the : - Eyepiece / Ocular Lens - Objective Lenses *High Power Objective *Low Power Objective *Scanner *Oil Immersion Objective
What is proper ways of handling and manipulation microscope?
Manipulate a MicroscopeInstructions1Set up the microscope on a flat surface. Always carry the microscope using two hands if the microscope must be transported from one area to another. One hand should support the bottom while the other hand is holding the arm. Once in place, remove the any covers and plug in the microscope.2Position the slide onto the stage. Clip it into or under the slide holders. Turn on the light from the illuminator under the stage. Center the slide the best way possible without using any focusing knobs or the eyepiece.3Look through the eyepiece, keeping both eyes open to avoid eye strain, while using the course focus knob to bring the stage and slide closer to the objective, which is the lens that extends below the eyepiece, until the object can be seen through the eyepiece. Use the fine focus knob (which will also be on the side of the microscope) to bring the image into sharper focus.4Center the object being viewed. Change the iris diaphragm under the stage using the level to open and close the iris. Change the amount of light entering the specimen as needed. Changing the amount of light going through the slide may show additional details not seen at higher light levels.5Change to the 10X objective which is the next longest lens by rotating the lens pieces. The object should appear larger and only require using the fine focus knob to bring it into sharper detail. Use the iris diaphragm to change the amount of light entering the slide. Continue to the 40X objective and repeat. Each time the object will appear larger and you will be able to see less of the object at any one time while viewing.6Lower the stage and add one or two drops of immersion oil to the slide. Change the microscope to the 100X objective. Slowly raise the stage using the course focus until the objective is touching the oil. Use the fine focus knob to bring the object into sharp focus. Clean the slide and objective with lens tissue after use.7Return the stage to the lowest level. Change the objective back to the 4X lens. Unplug the machine and replace any covers. Carefully return the microscope using both hands to where it is stored.
For what purpose would you adjust each of the following microscope components during a microscopy exercise?
Although the Lab Manual describes it, here it is... Iris Diaphragm: used to regulate the amount of light entering the lens system. Coarse-adjustment knob: used to raise or lower the body tube of the microscope. Fine-adjustment knob: used to bring specimen into sharp focus. Condenser: controls the maximum numerical aperture and to move the condenser itself. Mechanical stage control: used to adjust the slide vertically and/or horizontally to bring slide into central opening of the objective.
What is low power objective in a microscope?
A low power objective in a microscope is a Small Lens with Low Magnifying Power. A microscope head with two eyepiece lenses, one for each eye. Generally this term is used in describing a high power (compound) microscope. With a low power microscope we say "stereo" head because, unlike the compound microscope, the stereo has a separate objective lens for each eyepiece lens, producing two independent paths of light, one for each eye. In the compound microscope with a binocular head, there are two eyepiece lenses but still only one objective lens and you will not get stereo vision. Hope this helps.
Enumerate the parts and functions of compound microscope?

What is the major function of each major part of a compound and dissecting microscope?
The compound microscope consists of an arm to support base, lens to see through, stage to place the slides, illuminator for steady light and rack stop for adjustment. A dissecting microscope consists of diopter for adjustment, lens for viewing, focus knob for focusing on the subject and rotating objective turret for zoom control.
What is the function of revolving nosepiece of the microscope?
Allows each objective to be swing into position. ---Co0leTs24

Does a compound microscope have one lens?
Most microscopes have 4 to 5 lenses. The lenses are:The three Objects (which are the three things that you use to microscope)The lens that you you put your on.And the mirror lens.
What is the total magnification of a compound microscope?
The ocular lens are 10x magnification. Objective lens are 4x, 10x, 40x, 100x magnification. So once an objective lens is selected, the total magnification would be given by its product with the 10x magnification of the ocular lens. For example, if objective lens selected is 40x, total magnification would be: (10x)(40x)=400x total.
What is the function of thE REVOLVING?
It is to change the objective of the lenses in the microscope
What is the total magnification for each lens setting on a microscope with 15x oculars and 4x 10x 45x and 97x objective lenses?
Multiply the Ocular strength by the Objective strength. In this case: 60x, 150x, 675x, 1455x
