How big would the specimen look?
the specimen is the objective the microscope and a parts of microscope
Under which magnification would the distance between the objective and the specimen being observed be the least?
1000x
How many times is the image of the e magnified when you view through the high power objective 40?
It depends on what magnification the ocular lens is (usually 10x), then you multiply that by the objective lens magnification (what you said to be 40x). So the microscope would magnify your specimen by 400 times.
Why is it important to focus specimens under the Low Power Objectve before observing it under the High Power Objective?
It allows you to center the specimen, and if it is set up correctly, then when you switch objectives it should still be there and only need fine focusing. It also reduces the chance of crushing the specimen and/or breaking the slide or the lens as the LPO is further away from the slide than the HPO.
Which part of a light microscope would most likely be damaged if the coarse adjustment is improperly used while a specimen is being observed under high power?
The high powered lens could be damaged. Also, the slide can be broken.
What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x?
400x
How big would the specimen look?

Which objective would be better to use when using a scanning slide?
Might add extra, but i really hope this helps! scanning objective - for locating the specimen on the slide (= low power objective) high power objective - magnifies the specimen to provide a detailed image coarse adjustment - used to focus the image when using low power diaphragm - used to adjust the amount of light passing through the specimen revolving nosepiece - holds the three objective lenses - it can be rotated to change the objective in use arm - holds the stage and the lens system - can be used to tilt the microscope (but not advised) substaGe lamp - provides a uniform illumination (more reliable than daylight !!)
What is the objective lens on a microscope?
An optical microscope used in a laboratory would have 3 different types of lenses.They are :-(1) Condenser lens- directs light to the specimen if there is no in built light source.(2) Eye piece - lens close to the eye of the observer which magnifies the image created by the objective lens.(3) Objective - These are the lenses which are positioned closest to the specimen mounted on the stage of the microscope which magnifies the specimen. There could be several objective lenses in an optical microscope, generally three. The low power objective (usually magnifies 4 times), mid power objective (usually magnifies 10 times) and the high power objective (usually magnifies 40 times).
What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40 x and an ocular lens power of 10 x?
10 x * 40x = 400x
Under which magnification would the distance between the objective and the specimen being observed be the least?
1000x
Which objective would you use to initially locate the specimen high or low power objective?
low-power because there's more of a field of depth where you can see more rather then in the high power you can't see as much and only one object will be in focus while everything else would be blurry in the background (if there's more then one thing in the slide)
What is the total magnification if you view an object using a 40x objective lens and the eyepiece of the microscope is at 5x magnifying power?
The total magnification would be 200x, since the total magnification is the magnification of the objective lens X the magnification of the eyepiece.
How many times is the image of the e magnified when you view through the high power objective 40?
It depends on what magnification the ocular lens is (usually 10x), then you multiply that by the objective lens magnification (what you said to be 40x). So the microscope would magnify your specimen by 400 times.
If a microscope had a power of magnification of 200x what would the power of the objective lens be if the eyepiece lens is 10x?
20x objective
When using the high power objective which focus knob do you use?
The fine adjustment knob is used with the power objective on the microscope. Since the objective is already at the highest objective possible for that microscope, using the coarse adjustment knob would focus to much on the object making the details harder to read. Using the fine adjustment knob, you are able to see the fine details within the object or organism you are studying. The higher the power, the finer the knob and the lower the objective, the coarser the knob and objective.

It allows you to center the specimen, and if it is set up correctly, then when you switch objectives it should still be there and only need fine focusing. It also reduces the chance of crushing the specimen and/or breaking the slide or the lens as the LPO is further away from the slide than the HPO.
