Nanometer - Study guides, Class notes & Summaries

Discuss the basics of radiologic science CORRECT ANSWER X-rays fall between the gamma ray and ultraviolet wavelength range; xrays have between 0.03 to 3 nanometer wavelengths. (associated with short wavelengths) Describe how xrays are produced CORRECT ANSWER Xrays are the result of a high impact of a large volume of heated negatively charged electrons with a hard surface. When this impact occurs, the electrons rupture with the conversion of electrons to x-radiation. Describe the elements o...

Module 3 BIOD 171 1. True or False: A nanometeris longer than a micrometer.: False. A nanometer is 1,000 times smaller than a micrometer. 2. What is the total magnification (relative to your eye) of a sample imaged with a 60x objective and a 10x eyepiece? Show your math.: 60 x 10 = 600x magnification 3. Assuming a fixed ocular, identify the part of the microscope you would adjust to enhance the magnification of a sample. A. Objective B. Condenser C. Iris diaphragm D. Eye piece: A. Onl...

A nanometer is defined as: A. 10-3 B. 10-6 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 nanometer is 1,000 times smaller than a micrometer. 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 mor...

1) Robert Hooke coined the term cell when studying thin slices of cork. These were the first cells observed because . 1. A) dead plant cells; the thick cells walls did not require high resolution or magnification to view 2. B) dead animal cells; they were immobile and did not need to be fixed before viewing 3. C) compartments; they were actually the result of multiple cells that had merged and died to form large compartments that were easy to view 4. D) immune cells; they produce antib...
