to work out a microscopes magnification, you multiply the magnifications of its two lenses together. so the magnification of a microscope with a x5 eyepiece lens and x10 objective lens is 5 x 10 = x50
the detail obtained by a microscope also depends on its resolution.
resolution is the smallest distance between 2 points that can be distinguished as separate points
the electron microscope was developed in 1930s, instead of light, beams of electrons are used to form an image by passing through a speciman
electron microscopes can magnify up to x 2000000 with resolutions down to 0.0000002mm.
.
what determines how good a microscope is at showing small details? magnification
what has the development of the electron microscope allowed us to do? see the structure of cells in greater detail
what units are used for very small sizes?
Nanometers / picometers
why electron microscope images show more detail than light microscopes?
electron microscopes use beams of electrons instead of light, which builds up a better image
give the highest resolution of electron microscopes in micro, nano, and picometers?
