what are the three types of microscopes
light, SEM and TEM
3 of 5
what is the difference between SEM and TEM
TEM - has a magnification of x2 million a resolution of 0.2Nm, image in black and white and in 2D TEM - magnification of x500,000 resolution of 10Nm image in 3D and colour can be added to it on a software
