Question

The focal length of eyepiece and objective lens of certain microscope is 2.5 cm and 16mm respectively the distance between objective and eyepiece 22.1 cm. treat all lenses as thin. what should be the distance of the object from the objective lens and what is the linear magnification produced by the objective?Please help as fast as you can​

Answer 1

Explanation:

for the image to form by objective is at infinity then the object distance must be f=2cmf=2cm

and the final image is formed at focus of eyepiece i.e, f= -3cmf=−3cm

distance of image from objective lens is 15-3=12cm15−3=12cm
