C.10-9


D. 10-12 C. A nanometer is defined as one-billionth of a meter.


2. True or False: A nanometeris longer than a micrometer. False. A

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).
