- The numerical aperture of the an objective lens: indicates magnification indicates the clarity indicates light capturing ability indicates the approprite usewhat happens to the field of view as magnification is increased useing shccdssively higher power objective lensWhat is the rule for determining total magnification? A. Ocular lens magnification + objective lens magnification = total magnification B. Ocular lens magnification - objective lens magnification = total magnification C. Ocular lens magnification x objective lens magnification = total magnification
- All other things being equal, the objective lens with the highest value for numerical aperture (N.A.) will always have the lowest______? A. Field Of View B. Magnification C. Image Quality D. Limit Of ResolutionHow can you improve contrast when viewing a specimen?. What should you do if you have difficulty focusing in high power?. Why is important to use the fine adjustment nob only when focusing while using the high dry objective lens?Total Magnification is obtained by Select one: A. Magnifying power of both the objective lens and eyepiece B. Magnifying power of eyepiece C. Magnifying power of condenser lens D. Magnifying power of the objective lens
- John observed bacteria at 100X under the oil immersion and then decided to go back to 40X objective by raising the oil objective a little to avoid the damage to objective lens. Critique his technique.To obtain a 400X magnification image you may choose a 40X objective lens with a 10X projector lens, or a 20X objective lens with a 20X projector lens. What are the differences in their image quality?Match the lens (condenser, high-dry, low-power, ocular, or oil immersion) to its description.This objective lens provides the highest magnification.
- Explain why an image must be centered in the field of view when using low power before moving to a high power magnification.You should always position the cells or tissues in the center of view before increasing magnification, becauseTrue-False Once focus is achieved at one magnification, a higher-power objective lens can be rotated into position without fear of striking the slide.
