🌟 How Light Microscopes Work
- Light Source: Light travels upward from the bulb or mirror
- Condenser: Focuses light onto the specimen
- Specimen: Light passes through the thin, transparent specimen
- Objective Lens: Collects light and creates magnified image
- Eyepiece: Further magnifies the image for your eye
- Eye: Sees the final magnified, illuminated image
💡 Key Principle: Light microscopes work by passing light through a specimen. This means specimens must be thin enough for light to pass through (transparent or translucent).
