Study Notes

Microscope Basics

The word "microscope" comes from the Greek words "mikros" meaning small and "skopein" meaning to look or see, literally meaning "an instrument to see small things".

Magnification and Resolution

If there is increased magnification without improved resolution, it will result in an empty magnification, making the image appear larger but not clearer or more detailed.

Magnification Power

A magnification of '100x' indicates that the object appears 100 times larger than its actual size.

Calculating Total Magnification

The formula to calculate total magnification is: Total Magnification = (Objective Lens Magnification) × (Eyepiece Magnification).

Human Eye Resolving Power

The resolving power of the unaided human eye is approximately 0.2-0.3 millimeters, meaning it can distinguish two objects as separate if they are at least 0.2-0.3 mm apart.
