a) Draw a ray diagram to show the working of a compound microscope. Deduce a expression for the total magnification when the final image is formed at the near point. b) A compound microscope has an objective of focal length 1 cm and an eye piece of focal length 2.5 cm.An object has to be placed at a distance of 1.2 cm away from the objective for normal adjustment.Find the angular magnification and length of the microscope tube.

a) A simple microscope has a limited maximum magnification ( 9) for

realistic focal lengths. For much larger magnifications, one uses two

lenses, one compounding the effect of the other. This is known as a

compound microscope.

 

A schematic diagram of a compound microscope is shown below
