Biol 227 Lab Exam; Questions and Answers 100% Correct body of microscope Answer-arm and base light source Answer-Projects light upwards through the diaphragm, the specimen, and the lenses. Has on/off switch and intensity knob eyepiece Answer-Contains the ocular lens ocular lens Answer-magnifies the image 10x total magnification Answer-objective lens x ocular lens field of view Answer-The area visible through the microscope eyepiece

Why is oil immersion used? To reduce the amount of light rays that are refracted away from the objective lens. It increases numerical aperture and maintains a uniform light speed. increase the resolving power of a microscope. Prevents refraction of light. What parts of the microscope does light travel through? Illuminator-The light source for the microscope.Diaphragm-Controls the amount of light entering the condenser. Condenser lensFocuses light through the specimen. How do you calculate t...
