A person with a normal near point (25 cm) using a compound microscope with objective of focal length 8.0 mm and an eyepiece of focal length 2.5cm can bring an object placed at 9.0mm from the objective in sharp focus. What is the separation between the two lenses? Calculate the magnifying power of the microscope,

Text Solution

Verified by Experts

Angular magnification of the eye-piece for image at 25cm
`=(25)/(2.5)+1=11, |u_(e)|=(25)/(11)cm=2.27cm, v_(o)=7.2cm`
Separation = 9.47 cm, Magnifying power = 88
