Question

In a compound microscope the objective and eye-piece have focal lengths of 0.95 cm and 5 cm respectively and are kept at distance of 20 cm. The last image is at . Calculate magnifying power.

• A. 95
• B. 94
• C. 94/6
• D. None of these

Answer 1

Answer: (D)

None of these

Answer 2

If final image is at 

then u_e = 5 cm, v₀ = 20 – 5 = 15 cm

MP = m₀ × m_e =

= $\left( \frac { 25 } { 5 } \right)$ » – 74
