SUMMARY
The discussion centers on calculating the distance from the sample to the objective lens of a microscope with a tube length of 160 mm, achieving a total magnification of 800X using a 40X objective and a 20X eyepiece. The relevant equations include M=(Meyepiece)(Mobjective), Meyepiece=25/Feyepiece, and Mobjective=-L/fobjective. The focal length of the objective was determined to be 0.4 cm, and the focal length of the eyepiece was found to be 1.25 cm. The next steps involve using these focal lengths to calculate the distance to the sample based on the principles of relaxed viewing and parallel light rays.
PREREQUISITES
