When trying to look at an object that is too small to see with the naked eye. The kind of microscope will depend on how small the object is.
After every use is probably the best time. Also, before is helpful as well.
scanning electron microscope
we would use a light microscope
A transmission electron microscope (TEM) would be best for looking at the internal structures of a cell.TEM uses a beam of electrons to produce a detailed image of cell structures with high resolution around 0.1 nm.
Electron microscope which is ten thousand times better than a normal one
A scanning electron microscope would be the best choice because the electron microscope can achieve a much greater resolution than that obtained with the light microscope because the wavelength of electrons is shorter than that of light.
A compound light microscope with phase contrast or differential interference contrast (DIC) capabilities would be best to use if you want to observe living cells. These techniques allow for better visualization of cellular structures without the need for staining or fixing the cells, preserving their integrity and enabling real-time observation of processes such as cell division or movement.
The light microscope use the visible light; the electron microscope use an electrons beam.
an electron microscope
A confocal microscope or a live cell imaging microscope with time-lapse capabilities can be equipped to produce real-time images of cell movements. These microscopes use advanced technology to capture high-resolution images of living cells in motion.
We use light microscope because it is better for our eyes!!
A microscope is the best tool for a student to use to observe mitosis in an onion root tip.
