A nanometer is defined as: - ANSWER-10 -9 or one-billionth of a meter True or False: A nanometer is longer than a micrometer - ANSWER-False A nanometer is 1000x smaller than a micrometer Resolution and contrast are two critical factors that influence your ability to see an object. Explain each. - ANSWER-Resolution refers to the distance between two objects at which the objects can still be seen as separate. Poor or low resolution means two or more objects may appear as one. Contrast ...
