Explanation / Answer

Answer:

B. 1. This objective lens provides the highest magnification = Oil immersion

2. This objective lens provides the second highest magnification = High dry

3. This objective lens provides the lowest magnification = Low power

4. This objective lens has the shortest working distance = Oil immersion

5. The coarse focus knob should be adjusted only when using this objective lens = Low power

6. This lens collects an focuses light from the lamp on to the specimen = Condenser

7. This lens, also known as eye piece, often comes in pairs = Ocular

8. Diopter adjustments can be made to this lens = Ocular

9. A diaphragm is used to regulate light passing through this lens = Condenser

C. 1. Acetone is the safest solvent for cleaning an objective lens: False

2. Only lint-free optically safe soft tissue should be used to wipe off the microscope lenses: True

3. The total magnification capability of the light microscope is only limited by the magnifying power of the lens system: False

4. The coarse focus knob can be used to adjust the focus when using any of the objective lenses: False

5. Once the focus is achieved at one magnification, a higher-power objective lens can be rotated into position without fear of striking the slide: True

D. 1. (e) Both (b) and (c) are correct

the numerical aperture of the lenses, and the wavelength of light.

2. (e) the stage and the objective lens.

3. (c) parfocal
