Complete the calculations for total magnification produced by various combinations of the eyepiece and objective lenses. You may assume that the magnification for the eyepiece is 10X for each question.
1. When the scanning (4X) objective is used the total magnification will be:
2. When the low power (10X) objective is used the total magnification will be:
3. When the high power (40X) objective is used the total magnification will be:
4. When the oil immersion (100X) objective is used the total magnification will be:
