Why should you watch from the side before you lower the objective of your microscope?

Sometimes, if the stage is set high enough, the objective lens can hit or scratch the slide when it's changed, because each objective lens is a different length. From the back of the microscope, you cannot see if the lens is going to hit the slide or not, and run the risk of disturbing your sample. This problem can be prevented by looking from the side and stopping if it looks like the lens is going to hit the slide.
Watching from the side also helps to know if it is too low, or just in the right distance.

Why should you look to the slide before you lower the objective of your microscope?
so the objective lens will not touch the slide.
What is low power objective for a microscope?
The lower power objective for the microscope is the small lense on the microscope. The size usuall ranges at 4x on the microscope.
Why should you watch from the slide before you lower the objective of your microscope?
Movements viewed through the microscope are exaggerated quite a bit. As such, it's best to attempt to line up the object on the slide by looking at the slide directly, rather than through the objective.
What is a lower power objective?
The lower power objective is the lens on the microscope that gives you the lowest magnification. The exact magnification is 40x
Why should you watch from the slide before you lower the objectives of your microscope?

What is the proper procedure for focusing the microscope?
start with the lowest objective then adjest your focus. After, switch your objective if needed going from lower to higher
When using a microscope how much larger than normal does an object appear with lower power objective?
Not all microscopes have the same magnification for the lower power lens.
How should the light intensity control knob be set before turning the microscope on or off?
Any it really doesnt matter. But the lower is better.
A microscope has 20 X ocular eyepiece and two objective of 10 X and 43 X respectively?
lower power= 20 x 10= 200x higher power= 20 x 43= 860x
Microscope image centered and viewed on low first before high?
lower= further away than high
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.
What does high-dry mean on a microscope?
Hi there, i am a first year microbiology student and couldn't give you the most in depth answer, but...most microscopes have four different objective magnification lenses; 4x, 10x, 40x and 100x. High and dry is referring to your 40x objective lense, because it's the highest magnification you can look through a microscope before you should put oil on your slide. Putting oil over your slide at 40x or lower simply blurs your scope vision whilst placing a drop of oil at 100x increases the amount of light and resolution you see due to the affects of refraction. It makes your view clearer. I hope that helps.
