Microbiology Micrometer – 10-6 : One millioneth of a meter Nanometer – 10 –9 : One billioneth of a meter The naked eye can see objects clearly over 100 micrometers, but some cellular components can be as small as 0.2 micrometers in diameter What influences our ability to ? 1. RESOLUTION – Difference between two objects where objects can be seen as separate. The CLOSER the two objects are, the GREATER the RESOLUTION requirement 2. CONTRAST – Difference in light absorbance. The ...
