- The compound microscope can magnify the image of a tiny object up to 1000X.
- Principle of compound microscope:
- When a tiny object to be magnified is placed just beyond the focus of its objective lens, a virtual, inverted and highly magnified image of the object is formed at the least distance of distinct vision from the eye held close to the eye piece.
