To analyze:
The appearance of letter e through scanning objective of a compound microscope.
Introduction:
A compound microscope is an instrument that magnifies an object. A compound microscope uses transmitted light as a source of light. The light passes through the sample and that only thin material may observe. The different parts of the microscope performed different functions. The coarse adjustment knob moves the stage towards or away from the objective lens to focus widely. The fine adjustment knob moves stage slightly for more sharp focus. The objective lens has different magnification powers that depend on the type of model. The

- Assume you are observing the diatom pictured in Figure 1 using the 10X lens in a compound light microscope. You move to the 40X lens and then again to the 100X lens by only rotating the turret (remember that the lenses are parfocal), without making any other adjustments to the microscope. c) After making your adjustments, you notice that the midline of the diatom is in focus while the remainder is blurry. Explain, based on microscopy principles, why this has occurred Provide a description of the procedure to prepare an acidic stain of bacteria using Nigrosin as it would appear in the Methods section.arrow_forwardDescribe the process of bringing a specimen into focus using a compound light microscope.arrow_forwardIf a specimen is being viewed under a 40x objective, and the microscope has a 10x ocular lens, what is the total magnification? 1x 4x 10x 100x 400xarrow_forward
