Certainly! In a compound microscope, the objective lens is the one closest to the object being observed, and its focal length is short because it needs to gather light from a close distance and create a real image close to the eyepiece. This real image serves as the object for the eyepiece.
The eyepiece, on the other hand, acts like a magnifying glass for the real image produced by the objective lens. It has a long focal length to further magnify the real image and produce a virtual image that can be comfortably viewed by the observer's eye.
So, in summary:
- Objective focal length: Short
- Eyepiece focal length: Long
The focal lengths of the objective and the eyepiece of a compound microscope are 2.0 cm and 3.0 cm respectively. The distance between the objective and the eyepiece is 15.0 cm.
In compound microscope, the focal length of objective and eye-lenses are 1.2 cm and 3 cm respectively.
