BIOD 171 MODULE 3 EXAM Questions and Answers with Complete Solutions rated A+ A nanometer is defined as: - 10 -9 or one-billionth of a meter True or False: A nanometer is longer than a micrometer - 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. - Resolution refers to the distance between two objects at which the objects can still be seen as separate. Poor or low resolution means...

Biology 1406 Lab Exam 1 Collin College - Question and answers already passed Biology 1406 Lab Exam 1 Why is oil immersion used? - correct answer To reduce the amount of light rays that are refracted away from the objective lens. It increases numerical aperture and maintains a uniform light speed. increase the resolving power of a microscope. Prevents refraction of light. What parts of the microscope does light travel through? - correct answer Illuminator-The light source for the micros...

How does refractive power of a lens change if its radius of curvature decreases? - Answer-The power increases How does refractive power of a lens change if its radius of curvature increases? - Answer-The power decreases What is radius of curvature in case of a lens? - Answer-Flattener lens= larger radius of curvature. More rounded lens=lesser radius of curvature. How does refractive power of a lens change if its index of refraction increases? - Answer-Refractive power will increase Calc...

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...

Portage Learning: Microbiology Module 3 Already Graded A Define the measurements micrometer and nanometer. A micrometer (μm) is defined as being one-millionth of a meter and is commonly designated at 10-6 meters. A nanometer (nm) equals 10-9 m or one-billionth of a meter. What are the two critical factors that influence your ability to see an object? Resolution and contrast. Resolution refers to the distance between two objects at which the objects still can be seen as separate. Poor or low r...
