What are the differences between a light microscope a compound microscope a stereoscopic light microscope a transmission electron microscope and a scanning electron microscope?

Answer 1

A light microscope uses a series of lenses to focus light allowing small objects to appear larger. A compound microscope works as a light microscope except it uses more than two lenses to increase magnification. A stereoscopic light microscope can be simple (one lens) or compound (more than one lens) and uses two eyepieces.

A transmission electron microscope requires the object be in a vacuum and stained (usually with a heavy metal). The microscope fires electrons at the target and measures the diffraction allowing for a computer to generate an image.

A scanning electron microscope uses an electron beam to scan the target. It then generates an image by analyzing the variety of signals produced such as secondary electrons released, electromagnetic radiation, and electron deflection.

Also an electron microscope can observe a centriole, a tiny structure found in animal cells. Also to break down what a compound light microscope does is that it uses light and a curved piece of glass to make tiny structures appear larger. We can also see many other objects throw a microscope by taking a piece of cut Glass taking for example a piece of string and adding a drop of water then adding a small plastic thing and putting it under a COMPOUND LIGHT MICROSCOPE!!!!!!

Answer 2

Light microscopes use light whereas electron microscopes use electrons. This is because light has quite a long vave length - 350 to 550 nm and so that is the kind of resulution. that you have with one. Electrons have a much smaller wavelength (yes, electrons are waves - and particles) and so you have a much higher resolution (detail).

Answer 3

A compound light microscope is used for very fine measurements and is only used for observing thin substances. A electron microscope is for seeing tiny particles like organelles of a cell, or used to see electrons or neutrons etc.

Answer 4

They are microscopes get over it poeple.

Yeah well what if were doing it for school.... plus umm you spelled people wrong
