You don't want yucky stuff mushing itself onto your objective lens. Slide covers save you from constantly cleaning your lens.
it is use to place an item on and put it under a microscope to view
Because an air bubble, trapped between the slide and cover plate, shows as a dark'blob' under magnification. Using a drop of water to 'seal' the slide & cover plate together excludes the air - making the specimen more visible to the user.
A slide.
A glass slide: coverslip
The piece of glass used to observe specimens under a microscope is called a slide. Sometimes a thin piece of glass is used to cover the specimen. This is called a coverslip. Coverslips and slides can be made of glass, quartz or plastic, as long as these items are totally transparent and do not introduce any distortion. Sometimes the material may be tinted in order to add contrast, although this is usually done with dye.
A wet mount slide is when a solution is applied to a microscope slide with whatever subject is being studied, typically under a slip cover.

It should be placed under the clips.
A microscope slide and coverslip should be held by their edges due to leaving fingerprints and/or debris and how easily breakable they are. Leaving fingerprints or debris on either a slide of coverslip will alter the view under the microscope.

The lamp under the glass slid of the microscope is called the "bulb" lol. just kidding. i have no idea.
It changes the amount of light that's let in under the slide.
