Pregunta:

Compare and contrast light and electron microscopes

Autor: Rebeca Lorena Arce Fonseca



Respuesta:

They both magnify an image, and they both work based on wavelengths of light. However, an electron micrograph uses a beam of electrons (2-12 pm) and a light microscope uses visible light (400-700nm), so the shorter wavelength of the electron microscope gives it a higher resolution. Dead or alive organisms can be seen under a light microscope, but only dead ones in an electron. Light mic: resolution 0.2 micrometers magnification 500x, electron mic: 1 nm, resolution 500,000x
