- Using a good compound light microscope with a resolving of 0.3 micro meter a 10x ocular lens ,and a 100 x oil immersion lens, would you be able to discern two objects separated by 0.4 micro meter?0.2 micro meter? 300 neno meter ? Explain your reasoning.Differentiate between the limit of resolution of the typical light microscope and that of the unaided human eyes the relationship between the depth of field and magnification is that When magnification increases, the depth of field decreases. Name two procedures (steps) you should do to achieve the maximum resolution when using the oil immersion lens State the relationship between the working distance of an objective lens and its magnification power “The coarse focus knob can be used to adjust the focus when using any of the objective lenses”. Is this statement true or false? If it is false, please correct it. When using the oil immersion lens but you cannot focus, what should you should not do? And what you should do?
