Draw a ray diagram to show the working of a compound microscope. Deduce an expression for the total magnification the final image is formed at the near point. In a compound microscope , an object is placed at a distance of 1.5 cm from the objective of focal length 1.25cm. if the eye piece has a focal length of 5 cm and the final image is formed at the near point, estimate the magnifying the power of the microscope.
The magnifying power of a compound microscope can be increased by
The compound microscope is of magnifying power is 100.The magnifying power of its eyepiece " is 4.Then magnifying power of objective is
