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.
