Question: What is the correct setup for a compound microscope when a 30X angular magnification is desired, using an objective with a focal length of 1.25 cm and an eyepiece with a focal length of 5 cm?

Options

  1. AThe separation between the objective and the eyepiece should be 7.5 cm.
  2. BThe separation between the objective and the eyepiece should be 11.67 cm.
  3. CThe object should be placed 5.5 cm from the objective.
  4. DThe object should be placed 11.67 cm from the objective.

Correct answer

B. The separation between the objective and the eyepiece should be 11.67 cm.

Step-by-step solution

Correct Option is : (B) The separation between the objective and the eyepiece should be 11.67 cm.
