Questions
If the focal length of objective and eye lens are 1.2 cm and 3 cm respectively and the object is put 1.25cm away from the objective lens and the final image is formed at infinity. The magnifying power of the microscope is
detailed solution
Correct option is B
m∞=v0u0×Dfe From 1f0=1v0−1u0 ⇒1(+1.2)=1v0−1(−1.25)⇒υ0=30 ∴|m∞|=301.25×253=200Talk to our academic expert!
