n sin theta in most microscope have value = 1.2 and 1.4
therefore:
R. P. = 0.5x500nm/ 1.25 = 200nm = 0.2 microns.
(conv. 1000nm = 1micron).

1.) you place a stage micrometer on a microscope and focus in it so the stage micrometer and ocular micrometer are alighned at zero. you observe that 20 divisions of the ocular micrometer aligns with 0.15 millimeters on the stage micrometer, when using the 40x objective with a numerical aperature of 0.80. the ocular lens (eyepiece lens) has a power of 10x. You then remove the stage micrometer and place a slide containing cells onto the microscope and find that...
