Go slowly. Ask why. Make it yours.
PRACTICE / Microscopes
Multiply the two optical stages
A microscope objective produces a real intermediate image with linear magnification magnitude 12. The eyepiece has focal length 5.0 cm and forms the final image at infinity. Use near-point distance D = 25 cm for the reference unaided view.
Find the total angular magnification magnitude.
Organize the givens & assumptions
- Objective |mo| = 12
- Eyepiece fe = 5.0 cm
- Reference D = 25 cm
Paraxial thin lenses, relaxed-eye final image and the stated near-point reference.
- A
- B
- C
- D
