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.
I think you mean electron microscope.
The instrument that is used to study cells is a microscope.
Scanning electron microscope - SEM
The Compund light microscope allows people to view living cells. With the electron light microscope peole can only view dead cells but with very high detail. The electron microscope is also much more expensive than a compound ligh microscope. The compound light microscope is also much easier to transport from place to place, as the electron microscope is not.
the optical microscope is a type of microscope that uses visibal light and a system of lenses to magnify images of small samples
it means to see through the microscope on a field
a place where the background of the object is called field in microscope
"The parts"ex. "les parties du microscope" would be "the parts of a microscope"
a microscope's resolution specifies the smallest object you can see and distinguish from other nearby objects.
i assume you mean what does soenthing put in viewing area of a microscope it will magnify that object
magnification.
wet mount
Microscopic means too small to see with the unaided eye, so you need to use a microscope to see it.
too see
the ability of a microscope to distinguish fine details and differentiate between two very close objects (#spreadthelove)
I think you mean electron microscope.
On a microscope, the distance from the shoulder on which the eyepiece rests to the shoulder where the screw-in objective is located (nominally 160 mm).
