Question options: Adjusting the iris diaphragm Lowering the stage Turning off the substage condenser light source Changing the objective lensThe significance of using immersion oil when using 1OOX objective lens is The significance of using immersion oll when uskng 100X objective lens is: It will increase the contrast by having same refractive index as the lens, loss of light by refraction, reflection and diffraction is minimized. the specimens need not be killed, fixed and stained more light is captured for better illumination, allowing the specimen to fluoresce i. il. iii. iv. A light microscope should have the following features contrast Resolution magnification fluorescence ii. iv.What are the light sources used in UV-vis spectrophotometry.give ans
- Why do you need to always focus slides initially using the x10 objective, even if you wish to usea higher magnification? (Use for report, write more as u can~)The objective lenses of the microscopes used in this course are all parfocal. What does having parfocal objective lenses mean? Question options: The slide has to be moved away from the objective lens (i.e., lowered) when switching between objective lenses. None of these choices The objective lenses have optimized light gathering capability. Once in focus, you may switch between objective lenses with only fine focus adjustment required.Which of the following affect the resolution of a specific objective lens? CHECK ALL CORRECT CHOICES.
