Sample Data

Front Define Resolution
Back The minimum distance between two points where they can still be observed as two different objects
Front Explain artefact
Back - something that results from the way specimen is prepared (usually complex preparation) - human error- Can appear on micrograph but is not part of actual cell - example = air bubbles
Front The relationship between wavelength and resolution
Back Optical Microscope = LIGHT has a long wavelength, so the image produced has a lower resolutionElectron Microscope = ELECTRONS have shorter wavelength, so image produced has higher resolution NOTE = TEM HAS HIGHER RESOLUTION THAN SEM
