Basic microscope TRUE OR FALSE?

the first is false because in high power, you should use the fine adjustment because the coarse is too much when looking at a specimen that close. The second is true. The diaphragm is under the stage and has different sized holes to allow different amounts of light through. For the third question, the pointer is used to position a slide on the stage. This is only important, though, if you plan on using high power. Use a lower power first to center the slide or object on the slide. Then, you can turn it to high power and the object should be somewhere in that view if you had it centered correctly
