Do electron microscopes use visible light like compound light microscopes do?
utilising a mild microscope, you will discover cellular partitions,?vacuoles, cytoplasm, chloroplasts, nucleus and?cellular membrane. mild microscopes use lenses and mild-weight to amplify cellular areas. besides the undeniable fact that, they frequently can pass as much as 2000x magnification which isn't sufficient to make certain many different tiny organelles.
no. They use a stream of electrons. The smallest thing that you can see with visible light is determined by the wavelength of light. It's pretty small, a few hundred nanometers depending on the color. Electrons are much smaller though, so that's why they have greater resolution than visible light. An electron microscope can resolve detail at the level of pico meters, which is 1000 times smaller than what you can get with visible light. Usually, the subject that you want to observe with an electron microscope is coated with gold so that more of the electrons will reflect off of it. And then of course, the image that you see has to be colorized. There's a great wiki article linked below.
