A typical red blood cell subtends an angle of only 1.7×10−5 rad when viewed at a person's near-point distance of 25 cm. Suppose a red blood cell is examined with a compound microscope in which the objective and eyepiece are separated by a distance of 13.0 cm .
Given that the focal length of the eyepiece is 2.8 cm , and the focal length of the objective is 0.41 cm , find the magnitude of the angle subtended by the red blood cell when viewed through this microscope.
