Which microscope has the highest potential magnification? comparison microscope scanning electron microscope compound microscope stereoscopic microscope?

electron microscope

Explanation:

An electron microscope is a microscope which uses an electron beam to illuminate a specimen and it creates an enlarged image of that specimen. This microscope exhibit a very high resolving power as compared to light microscopes. This is capable of obtaining very high magnification. Some of the electron microscopes can magnify an image of the specimen upto 2 million times.

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
