Focal Length:
Imagine a microscope objective lens as a lens that gets thinner and thinner towards the bottom. Focal length refers to the distance between the optical center of the lens and the focal point, where light rays converge after passing through it. Lenses with shorter focal lengths bring objects closer to the focal point, providing higher magnification.

Magnification Power:
The magnification power of an objective lens is indicated by a number, such as 10x, 20x, or 100x. This number represents the ratio of the image size seen through the lens to the actual size of the object. For example, a 20x objective magnifies an object 20 times its original size.

Resolving Power:
Resolving power is the ability of a lens to distinguish between two closely spaced objects. Lenses with superior resolving power can separate details that may appear as a single entity through lower-powered lenses.

The numerical aperture (NA) of an objective lens plays a crucial role in determining resolving power. NA is a measure of the cone of light that a lens can collect from an object. Lenses with higher NA have higher resolving power, allowing users to visualize finer details.

Conclusion:
Magnification power, focal length, and resolving power are key characteristics that determine the performance of objective lenses in microscopy.
