1. True or False: A nanometeris longer than a mi- False. A nanometer is 1,000 times
crometer. smaller than a micrometer.
2. What is the total magnification (relative to your 60 x 10 = 600x magnification
eye) of a sample imaged with a 60x objective
and a 10x eyepiece? Show your math.
3. Assuming a fixed ocular, identify the part of the A. Only the oculars (eyepiece) and
microscope you would adjust to enhance the the objectives contribute to the mag-
magnification of a sample. nification of the sample. Since the
A. Objective eyepiece is fixed, only the objectives
B. Condenser could be altered.
C. Iris diaphragm
D. Eye piece
4. What is the total magnification (relative to your 20 x 15 = 300x magnification
eye) of a sample imaged with a 20x objective
and a 15x eyepiece? Show your math.
5. True or False: Staining is often required to image True. Adherent, flat and unstained
a cell that is adherent and flat (thin). cells are almost invisible due to the
limits on both resolution and con-
trast. Therefore, cell staining is often
required to adequately image the
sample.
