BIOD 151 Portage Learning Microbiology Module 3 Questions And Answers 100% Solved A nanometer is defined as: 10-9 A nanometer is defined as one-billionth of a meter True or False: A nanometeris longer than a micrometer False. A nanometer is 1,000 times smaller than a micrometer. 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 se...

frequency correct answers The number of times a given event occurs in a given time; for a wave, the number of cycles that pass the observer in 1 second. Wavelength correct answers Horizontal distance between the crests or between the troughs of two adjacent waves Photon correct answers quantum of electromagnetic energy; carries an amount of energy that depends inversely on its wavelength Electromagnetic Radiation correct answers changing electric and magnetic fields that travel through ...

micrometer one millionth of a meter, 10^ -6 2. nanometer one billionth of a meter, 10^-9 3. Resolution the distance between two objects at which the objects still can be seen as separate 4. What happens if the resolution is poor? Poor or low resolution means two (or more) objects may appear as one. 5. Contrast the difference in light absorbance between two objects. 6. What happens if there is poor contrast? gives a high background and makes the visualization of multiple objects diff...
