How should you first focus on a specimen when using the microscope?
start by focusing with the lowest lens to make sure the slide is right and you can see the specimen them proceed to the next lens power and focus again just to make the view clear then proceed to the highest and focus one more time
When you see a specimen clearly down a microscope it is in?
FOCUS
Inability to bring the specimen into sharp focus?
be better
Function of draw tube in micro?
Moved up and down to bring the specimen in focus. ---Co0lets24
What is a microscope and how is it used?
A microscope is a scientific instrument with one or more lenses that enhances the view of smaller objects, for example, microorganisms (bacteria) and microsopic materials, which are too small to be seen with the naked eye. The eyepiece lens and objective lenses able to zoom in and out to enlarge and observe the specimens more clearly, with the objective lenses having a much better zoom-in ability. The eyepiece lens is at the top where you look into to observe the specimen. There are usually 3 or 4 objective lenses on a microscope held by a revolving nosepiece/turret, consisting of different times of zoom-in, e.g. 40x, 100x, 400x.... Also, there is a fine focus knob and a coarse focus knob. The coarse focus is for moving the objective lenses nearer/further away from the specimen while the fine focus is for fine-tuning the focus (usually when it is unclear). Use the coarse focus before the fine focus unless there is no need to zoom in on the specimen. Finally, an illuminator might shine a light on the specimen so that you can see it more easily.
When focusing with a microscope do you always focus toward the specimen?
true
What function of course focusing mechanism?
The coarse focusing mechanism is the rough focus knob on the microscope. It is used to move the objective lenses toward or away from the specimen.
What is the function of the focus of microscope?
The final focus? Its used for final focusing of the specimen.
Function of the fine focus on the microscope?
to easily adjust when you look the specimen and to focusing
After focusing on top of specimen what happens to the depth of focus as you turn the fine adjustment knob backward?
If the fine focus knob is turned backwards the depth of the specimen decreases. When the knob is turned forward the depth of the specimen increases.
If after focusing in low power only the fine adjustmentneed be used to focus the specimen at thehigher power the microscope is said to be what?

What are the microsope's parts and functions?
The main parts of a microscope include the eyepiece, objective lens, stage, light source, and focusing knobs. The eyepiece magnifies the image, the objective lens provides additional magnification, and the stage holds the specimen. The light source illuminates the specimen, while the focusing knobs adjust the focus of the image.
