A high voltage of minimum 50, 000 volts is necessary. Only dead(fixed) organisms can be viewed. This limits it as two close objects cannot be seen as separate. Light microscopes are typically capable of providing a resolution of up to 200 nm. The light microscope, so called because it employs visible light to detect small objects, is probably the most well-known and well-used research tool in biology. Thanks this has helped me alot with my science assessment! There are two basic parts in a microscope, the slide and the cell that hold it. The main difference between them is that in an electron microscope, a beam of electrons is used for magnifying the image of an object while visible light is used in the light microscope to magnify images of tiny areas of materials or biological specimens. Let's have a brief overview of these microscopes through a comparison chart, and move towards details. The differences between a light microscope and a electron microscope are mentioned below. Electron microscope - More than its high magnification capability, an electron microscope . (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(hs); A light microscope provides a magnification of up to 1500x, but 1000x is more common. No we cannot say this because electron microscope is dangerous and also give black and white image also it is not economical so light microscope is better. The resolution of a light microscope can be somewhat increased by better focusing the light, widening the opening of the light source and thereby increasing the amount of light coming through, and using different types of light with a shorter wavelength.
