What is the highest magnification possible today through a microscope?
606323
Accordigng to my biology book, a normal microscope has a highest magnification of 430x, a compound microscope can do 1800x, and an electron microscope can do over 100,000x.

The size of an object you can resolve with an optical system has a theoretical limit given by the wavelenght of the light you're using divided by the diameter of the optics multiplied by 1.22. If you plug the numbers in you find for a 1 foot diameter optical system at visible light (~400 nm) at an altitude of 100km, the smallest thing you could see is on the order of a foot, give or take (rough calculation). You could definitely not read a postage stamp or a wrist watch. Maybe a license plate with some bigger optics, but this is ignoring all sorts of atmospheric scintillation which screws things up.

It's a new hi-tech microscope. Click below. You'll have to translate, it's in german.

If you mean the three types of microscopes then it is optical, light and electron.

It's what you peer into. There's a diagram here:\n\nhttp://en.wikipedia.org/wiki/Optical_microscope

a double convex lens will magnify, i can't remember which ones reduce size, but i'm guessing some sort of concave lens, and lenses REFRACT light, while mirrors REFLECT light.

It's because of its better resolution NOT magnification. Magnification is just the number of times the image is larger than the object.\n The Resolution however can be defined as the ability to distinguish between two seperate points.If two seperate points cannot be resolved , they will be seen as 1 point. Excited elecrons behave like electromagnetic waves and have a much shorter wavelength than the shortest wavelength of visible light.. therefore have a higher resolution , as a result the nuclear envelope , nuclear pore, the double membrane of mitochondria ..etc can be seen with the electron microscope even with the same magnification of the light microscope...

Look at it only through a magnifiying glass.

Magnification is dimensionless\n\nWhat is the focal length of the concave mirror in b\n\nConvex mirror has wider field of view.

Electron microscopes, which use beams of electrons instead of light, are designed for very high magnification usage. Electrons, which have a much smaller wavelength than visible light, allow a much higher resolution.\n\nThe scanning electron microscope (SEM) is a type of electron microscope capable of producing high resolution images of a sample surface. Due to the manner in which the image is created, SEM images have a characteristic three-dimensional appearance and are useful for judging the surface structure of the sample.\n\nThere are some great pictures and more info at http://en.wikipedia.org/wiki/Scanning_electron_microscope

Here are just a few:\n\nSimple light\nCompound light\nDisecting light\nConfocal\nScanning electron\nTransmission electron\n\nI'm sure you could do a Google search on "microscopes" and find what you're looking for.

You cannot see most cells with an ordinary microscope, but a scanning electron microscope can magnify thousands and thousands of times...;
