Help! Please. MICROSCOPES!?
1) What is the total magnification of a compound microscope, which is 5x ocular and aims to 10x? A. 2x B. C. 15x D. 25x 50x 2) Which of the following statements about the high power objective is TRUE? A. Can be used with the coarse adjustment knob. B. It has been an increase of 10 on the Most microscopes for students. C. In position, is located near the specimen mounted slide. D. Usually the only objective of a compound microscope. 3) What is an advantage of using an electron microscope? A. large increase in B. ability to stain specimens of C. ability to photograph images specimens D. ability to see the movement in living cells 4) If the total magnification is 45x and 15x eyepiece, which is the power of the objective? A. B. 30x C. 3x 10 D. 1
Questions 1, 4: You always multiply the increase in all lenses. I'm going to do simple math. Question 2: Do I need to be careful with high power objectives expansion because they are so close to the slide. For these reasons, never use the coarse adjustment. Question 3: Most of needed scanning electron microscopes coating samples of a material, usually gold. This avoids the use of live specimens. It gives high-resolution images of the small scale of features what you are seeing.
