Homework Answers
| Lens | total magnification |
| 10X ocular lens | objective lens magnification* 10x |
| 4X scanning objective lens | 4x * 10x = 40x |
| 10x low power objective | 10x * 10x= 100x |
| 40x high power objective lens | 40x * 10x= 400x |
| 1000x oil immersion objective lens | 1000x * 10x = 10000x |
Total magnification= Magnification of the eyepiece * magnification of the objective lens.

Which of the following statements are correct?
Which of the following statements are correct? The three objective lenses we have in the lab have individual magnifications of 4x, 10x and 400x If the total magnification is 400X and the ocular lens is 10x, then the objective lens used must be 400x. Total magnification equals objective lens magnification times ocular lens magnification. The fine adjustment knob is only used when the microscope is on the low or high power, that is you should only use the fine adjustment knob at magnifications of...
