A. 10-3
B. 10-6
C.10-9
D. 10-12 C. A nanometer is defined as one-billionth of a meter.
2. True or False: A nanometeris

smaller than a micrometer.
1. Resolution and contrast are two critical factors that influence your ability to see an object. Explain
each. Resolution refers to the distance between two objects at which the objects still can be
seen as separate. Poor or low resolution means two (or more) objects may appear as one.
*Contrast is the difference in light absorbance between two objects. Poor contrast gives a
high background and makes the visualization of multiple objects difficult. For instance, trying
to identify 2 dark colored objects at night (low light = low contrast) versus the same 2 objects
in the middle of a sunny afternoon (bright light against 2 dark objects = high contrast).

would adjust t. A nanometer is defined as:
