Remember: no copy-pasting of material from the Web! 4.5 / 5 based on 4 ratings. Low magnification of up to 1,500x. Light microscopes use visible light and lenses to magnify the image of the sample. The differences between a light microscope and a electron microscope are mentioned below. Another difference is that the optical microscope is usually operated so that the image is a virtual one, while in the electron microscope the final image is invariably real and is visualized on a fluorescent screen or recorded for study on a photographic plate in traditional instruments ormore usually in today's laboratoryon a digital imaging Moreover, an electron microscope cannot be housed in just any spacious room. what is the differents between an electrick microscope and a non-electric microscope. Only dead(fixed) organisms can be viewed. It has high resolving power (0.001m), about 250 times higher than light microscope. I managed to find adequate information here regarding my research. Each of these microscopes has distinct features and is suitable for different purposes from the magnification of simple objects such as living cells to complex objects such as the details of a nucleus in a cell. I need to use this information in my essay, would be helpful to know the name of the writer of this post outline.
