What kind of microscope is found in most classrooms?
Optical, though to see smaller organelles and structures in higher resolution an electron microscope may be necessary.
Why must you be careful when lowering the coarse adjustment knob on a microscope?
Depending on the lens choice, the lens may need to be very close to the sample to focus. This is especially true with the higher magnifications.You don't want to smash the lens into your sample, damaging the sample and the lens.

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.
Inclination joint in microscope?
An inclination joint of a microscope is where the arm of the microscope connects to the base of the microscope. Many microscopes have a pin to hold these to objects together. If the microscope is equipped with the pin you can place one hand on the base and with the other hand you can grab the arm and rotate it back and forth. The inclination joint allows the microscope to tilt back for more comfortable viewing. Please note, there is no way to contain liquid specimens if you tilt your microscope back the liquid will spill to the ground or all over.midfielder_francis@yahoo.com
Why may it be necessary to continually focus a microscope?
It may be necessary to continually focus a microscope so as to get accurate results about a specimen. This will give you enough time to study any specimen.
Why is it necessary to be able to focus a specimen at different depths on the microscope?
because the subject may have different charactreistics at different depths
Why is it necessary for humans to drink water continually?
How may humans have you seen drinking continually? If it were necessary, we would have graduated from using our mouths to having a drip inserted in to us. Also, do some research on water intoxication.
When viewing an object through the high-power objective of a microscope not all of the objeect may be in focus why?
The object may be 3D. If it is, not everything inside the object will be focussed. For example, if you look at a plant cell, the focus must be changed to look at the different organelles.
What is the objectives in a microscope?
The objective on a microscope is comprised of a tube and one or more lenses, and may include a mirror as well. Its purpose is to gather and focus light, typically while magnifying the image, from the sample or object under study.

Which microscope has a potentially large working distance?
stereoscopic microscope is the most frequently used and versatile microscope found in a crime lab. Its wide field of view and great depth of focus make it ideal for locating trace evidence that may be found at the crime scene. Furthermore its potentially large working distance makes it quite applicable for the microscope examination of big bulky objects.
