it is beter than a normal one and can see microscophic things
The minuscule amount of water in the cup was not enough to survive on.
The compound microscope enables us to see microscopic objects more clearly than the naked eye or the simple microscope
miroscope is a useful tool for biologists because when they do the experiment in so tiny objects it will help to find out the solutions (as we cant see in our naked eyes).Thanks.
Depends on the mechanism of the microscope, but with an optical microscope, anything smaller than 1/4 the wavelength of the light being used (around 10-6 Meters) eg a virus.
The first person to make a microscope was Dutch fabric merchant Zacharias Janssen in the late 16th century. He created a simple microscope with two lenses that could magnify objects.
Yes, a compound light microscope typically has a higher magnification range compared to a simple microscope due to its multiple lenses and higher resolving power. This allows for better visualization of smaller details in specimens.
Thiomargarita namibiensis and Epulopiscium fishelsoni are probably the only two bacteria that you can see with the naked eye. They are both about half a millimeter in diameter.
Before you turn it on, make sure there is no damage to the miroscope. Then make sure to always start on the lowest (or smallest) objective lens. Make sure to use the coarse focus knob (the big one) on the lowest objective then the fine adjustment knob only (the small one) on the higher objectives.
The binocular tube in a microscope serves to provide a dual optical pathway, allowing the user to view specimens with both eyes simultaneously. This enhances depth perception and comfort during observation, reducing eye strain and improving overall visual acuity. Additionally, binocular tubes often allow for adjustments in interpupillary distance, accommodating different users' eye spacing for optimal viewing.
