The focal lengths of the objective and eyepiece of a compound microscope are 1 cm and 10 cm respectively. Length of the tube is 25 cm . If the final image is formed at infinity, the magnifying power of the microscope is:
- A \(7.0\)
- B \(3.5\)
- C \(35\)
- D \(70\)
Answer & Solution
Correct Answer
(C) \(35\)
Step-by-step Solution
Detailed explanation
Given the focal length of the objective \(f_o = 1\) cm and the focal length of the eyepiece \(f_e = 10\) cm. The length of the tube \(L\) is the distance between the second focal point of the objective and the first focal point of the eyepiece. For a compound microscope, when…
