Question

Answer 1

Less
The objective lens has a very small focal length. The object is placed just over F of the objective lens forming a magnified image. This image is the object for the eye lens and lies between focus and optical center of the eye less as it has a greater focal length as compared to the objective lens. Since the new object is between focus and and optical center, it forms a virtual, magnified image which falls on the eye.

The focal length of the objective lens of compound microscope is always ..........(less\more) than the focal length of eye lens.

A compound microscope has an objective lens of $1.0 c m$ focal length and an eye-piece of $2.5 c m$ of focal length. When the object is placed at $1.1 c m$ from the objective, the final image is at the least distance of direct vision. Thus, the magnification produced is
