An AS Biology lesson comparing light and electron microscopes. It explains magnification and resolving power, why electrons give a much higher resolution, and how transmission and scanning electron microscopes work, finishing with a comparison table.
What this presentation covers
- magnification and resolution
- resolving power and wavelength
- the light microscope
- how electron microscopes work
- transmission electron microscopy (TEM) and specimen preparation
- scanning electron microscopy (SEM)
- light versus electron microscope comparison
