Q Lab Exercise - Microscope Parts & Viewing Objects • Points 10 • Questions 5 • • Time Limit 10 Minutes • Allowed Attempts 3 Instructions Overview The following exercise will test your ability to: • describe the functions of the parts of the compound microscope • calculate total magnification • define field, working distance and parfocal Requirements You will need to set aside 15 minutes at a laptop or desktop computer in a distraction free room for each attempt. Grading This assignment is graded. Each of 4 fill-in-the blank questions is worth 1 point and 1 matching question is worth 6 points for a total of 10 points possible.
