What must be the focal length of the eyepiece

Reference no: EM13488992

The distance between the lenses in a compound microscope is 18 cm. The focal length of the objective is 1.5 cm. If the microscope is to provide an angular magnification of -65 when used by a person with a normal near point (25 cm from the eye), what must be the focal length of the eyepiece?
