Lab 1: Microscopy and the Metric System Part A: Microscopy Procedure: Identify the parts of the compound light microscope and their function. Response: a. Eyepiece: The lens the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens. b. Diopter Adjustment: Changes focus on one eyepiece and corrects for any difference in vision between the eyes. c. Arm: The arm connects the body tube to the base of the microscope. d. Coarse adjustment: Brings the specimen into general focus. e. Fine adjustment: Increases the detail of the specimen by minute adjustments. f. Nosepiece: A rotating turret that contains the objective lenses. g. Objective lenses: These lenses are used to view the specimen and are closest to the specimen. A standard microscope has several objective lenses that range in power from 4X to 100X. h. Stage height adjustment: Moves the stage from left and right or up and down. i. Aperture: The hole in the center of the stage that allows light from the illuminator to reach the specimen. j. On/off switch: This switch on the base of the microscope turns the illuminator off and on. k. Illumination: The light source for a microscope. l. Iris diaphragm: Adjusts the amount of light that reaches the specimen. m. Condenser: Gathers and focuses light from the illuminator onto the specimen. n. Base: The base supports the microscope. Question: Determine the total magnification given that you are using a compound microscope with the following objectives: 4X, 10X, 40X, and 100X. Assuming that the eyepiece contains a 10X power lens, the objective lens magnification would be 40X, 100X, 400X, and 1000X, respectively. 1. What is meant by the
