- If you have chosen the objective lens with 10x and the ocular lens magnification is also 10x. Then the total magnification will be 100x. True FalseThe numerical aperture of the an objective lens: indicates magnification indicates the clarity indicates light capturing ability indicates the approprite useWhy is it important to use immersion oil when using the 100X objective? What do you think would happen if you tried to view a slide using the oil immersion lens but forgot to add the oil?
- If your object appears too small, you can increase its size on a compound microscope by altering the Iris diaphragm. Zoom knob. Coarse focus. Objective lens.When you are using the 40X objective you should never use the: O iris diaphragm O fine focus coarse focus O pointerWhich of the following affect the resolution of a specific objective lens? CHECK ALL CORRECT CHOICES. Magnification Numerical Aperture (NA) Warelengthrofgnt combg tough t Field of View
- 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 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 focusHow does the numerical aperture of an objective lens affect resolution? Question options: Numerical aperture is the optical plane visible for each objective lens Numerical aperture decreases the amount of excess light on a specimen increasing the resolution and clarity Numerical aperture is the loss of light due to changes in density between the specimen and the objective lens Numerical aperture is a measure of the amount of light an objective lens can accept producing higher resolution and allowing smaller structures to be visualized with greater clarity
- True-False Once focus is achieved at one magnification, a higher-power objective lens can be rotated into position without fear of striking the slide.Match the lens (condenser, high-dry, low-power, ocular, or oil immersion) to itsdescription. Choices may be used more than once. This objective lens provides the lowest magnification.The most useful adjustment for increasing image contrast in lowpower magnification is a. closing down the diaphragm. b. closing one eye. c. opening up the diaphragm. d. placing a drop of oil on the slide. e. using a blue filter.
