Actually, it depends on the specimen which you are observing.. Suppose, if you are observing Tissues then you have to switch to 10X objective; but if you are observing mammalian cells or other cellular specimen then you have to switch to 45X objective...

But, if you want to observe microbial cells then you have to put a drop a drop of paraffin oil on the smear made on the slide and then observe it into 100X oil immersion objectivelens...

Which focusing knob on a microscope do you use when you first begin looking at a slide?

When you first begin looking at a slide under a microscope, you should use the coarse focus knob. This knob allows for quick adjustments to bring the specimen into general focus. Once the specimen is roughly in focus, you can switch to the fine focus knob for more precise adjustments.


Why should you always begin to use a microscope with a lower power objective?

You should always begin using a microscope with a lower power objective to locate and focus on your specimen more easily. Low power objectives provide a wider field of view, making it simpler to find the area of interest. Additionally, starting with lower magnification minimizes the risk of crashing the objective lens into the slide, which can damage both the slide and the microscope. Once the specimen is in focus, you can then switch to a higher power objective for detailed observation.


Describe briefly and systematise the manner of properly using a microscope?

To properly use a microscope, begin by placing the slide on the stage and securing it with stage clips. Start with the lowest power objective lens to locate the specimen, using the coarse focus knob to bring it into view. Once focused, switch to higher power lenses, using the fine focus knob for clarity. Always ensure to clean the lenses and cover the microscope when not in use to maintain its condition.
