Magnifying power of an astronomical telescope may be defined as the ratio of the angle subtended at the eye by the image to the angle subtended at the eye by the object. From the ray diagram we know that: P l C is the focal length of the objective and P l D is the focal length of the eye ..

The magnifying power of a compound microscope is defined as the ratio of the size of the final image (I 2 ) as seen through the microscope to the size of the object as seen with a naked eye. Image Formation in a Compound Microscope = m o b j e c t i v e x m e y e p i e c e = m o x m e Whe..
