A student looks at an onion epidermis through a microscope of eyepiece lens x10 and objective lens x40. What is the total magnification?
Answer and explanation
Correct answer: D. x400
- Step 1: Total magnification = eyepiece x objective = 10 x 40 = 400. Answer: x400. Why not the others: x50: That adds the two lenses instead of multiplying. x4: That divides 40 by 10. x4000: That multiplies by 10 once too often.
