AQA A Level Biology Microscopes
| 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 |
