You use the 3 objective lenses of a compound microscope to switch powers. There's LOW, MEDIUM, and HIGH power. With LOW power, you can magnify what you're looking at. With HIGH power, you can see things that you can't see with a naked eye.
The objective lens with the lowest magnification (i.e. lowest number) will have the largest field of view. This is generally a x4 objective. This along with a x10 eyepiece gives x40 overall. This may give a field of view with a diameter of around 4.5mm.
high objective lens has the largest diameter high objective lens has the largest diameter
Low power lens gives the widest field of view and makes it easier to find the specimen when you look through the microscope
The oil immersion lens @100x
scanning power objective
Scanning
40x
Brightfield microscopic illumination is used mainly to examine stained specimens, ie blood samples, cellular details, etc. It can also be used to examine unstained specimens that are not transparent......... Zeiss Guy
The organism moves to different levels in the wet mount.
Field of view will decrease as the aperture remain same but things become larger and so we can see smaller area after magnification
a dot diagram represent the electron configuration of a compound. in the case of K2SO4. there would be two K(Potassium) with one dot to show its one outside electron. S(Sulfur) with two dots for it's 3S Field and four dots for its outer P Field. Four O(oxygen) with the same dot pattern as sulfur. arranged in a pattern consistent with the shape of the compound based on what electrons are shared with which atom
This is because the crystal lattice is broken down and there are free mobile charged ions in solution that can move in the electric field and conduct current.
Microscope objective lenses are the lenses that you can select on the microscope to change to field of view and magnification.
how can the field of view on a compound microscope be made brighter
No its actually the opposite
As the magnification of the objective increases, the FOV decreases

Low power objectives cover a wide field of view and they are useful for examining large specimens or surveying many smaller specimens. This objective is useful for aligning the microscope. The power for the low objective is 10X.
The lens with the smallest magnification has the largest field of view.( usually 4x)
there are seven type of microscope.they are (1)Electron microscope (2)compound microscope (3)light microscope (4)scanning electron microscope (5)transmission electron microscope (6)dark field microscope and (7)light field microscope
The field of view becomes smaller when magnification increases.
If only half your viewing field is lit, twist objective lenses until they click into place.
To locate the exact site in the microscope field that you want to magnify.
The changes in the field of view and the amount of light when going from one low to high power using the compound microscope is 40X for (LOW) And 100X for (High).
