Step by step
Solved in 2 steps
- What is the magnification power of the objective lenses? How does the eyepiece compare to the objective lens? What is a magnification power? Differentiate between the fine and the coarse adjustment knobs.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?Why 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?
