Question

3. What is the difference between magnification and resolution? Magnification = enlarge What is the purpose of placing immersion oil on the slide? Immersion oil reduce scattering of light or refraction, Explanation @ the Botton! 5. What are the advantages of electron microscopes as compared to light microscopes? Electron has very small wave length Compaled to visible lights 6. Give at least five major differences between prokaryotic and eukaryotic cells. 7. If the ocular magnification is 10X and the oil immersion objective is in place, what is the total magnification? Label the following microscope parts Arm, Base, Course adjustment knob, Ocular, Oil Immersion objective. Fine adjustment knob, Revolving nose piece, Slide adjustment knobs, Sub-stage condenser, illuminator.

Answer 1

of Magnification microscope is the enlargement of object looking at Resolution of microscope as two distinct points a at the object looking at it's ability to let identify a minimum distance on to the back the light oil rediorects Immersion 1 eye , helping us better view of object. o on electron microscope, electron beam is used that helps in obseeking very small objects easily untile in light microscope whese light is used. 1.
