Pretty self explanatory. Because they are too small to see with the naked eye. Also, microbes are generally see thru and have to be stained to see them easier under a microscope.
The compound microscope is a light microscope that uses light to "see" microbes. Viruses are too small.The electron microscope uses electrons to "see" microbes or viruses.
They are both. Microbes are just small living things which we need a microscope to see.
The microscope that is used to see internal structures of cells in a natural state is the compound light microscope. The microscope has a lens and light that allows it to see the internal structures of a cell clearly.
microbes are stained so they can be visualised under a light microscope.
You don't need laser light. Normal light will do, for many microbes. You DO need a microscope, since they are way too small to be seen with the naked eye.

A phase-contrast microscope is typically used to view unstained living microbes, as it enhances contrast and allows for visualization of transparent specimens. A polarizing microscope is used to examine urine specimens for evidence of kidney stones, as it can help identify the unique crystalline composition of the stones.
