- If we used the 365nm setting on the UV light box would this have caused more or less UV light damage, explain why?Which of the following is not required for a UV-vis absorption spectrophotometer? Group of answer choices camera detector monochromator light sourceThe total magnification achieved when using a 100× oil immersion lens with 10× binocular eyepieces is a. 10×. b. 100×. c. 200×. d. 1000×. e. 2000×.
- Resolution is __________ with a longer wavelength of light.a. improved. c. not changedb. worsened. d. not possibleResolution is ______with a longer wavelength of light. a. improved c. not changed b. worsened d. not possibleYou should always position the cells or tissues in the center of view before increasing magnification, because
- To alter the amount of light coming through the stage someone should adjust the: Group of answer choices 1. eye pieces 2. coarse focus 3. objective 4. iris diaphragm 5. fine focusSal said that the microscope had a total of 400x magnification because the eye tube had a level of 10x and the objective lens had a magnification of 40x. Is sal correctWhich letter on the figure below represents the light intensity control?
- In absorption spectrophotometry: a. Absorbance is directly proportional to transmittance b. Percent transmittance is directly proportional to concentration c. Percent transmittance is directly proportional to the light path length d. Absorbance is directly proportional to concentrationYou can see your cells using the scanning and the 10x objective lenses. You cannot focus on anything when you add oil to your slide and move to the oil immersion objective. Your instructor comes over and wipes off your oil, turns over the slide, adds new oil, and moves the oil immersion objective into place. You can now focus on your cells. Knowing how immersion works, why couldn't you see the cells when the slide was upside down?How can a UV-Vis spectrophotometer be applicable in determining the absorbance/concentration of a colorless sample? Please answer in detail and clearly. Thank you so much!
