Lecture Notes on Light and Optics

Vocabulary flashcards based on lecture notes about light, electromagnetic radiation, lenses, and related concepts.

Electromagnetic Radiation

Electromagnetic radiation includes ultraviolet, infrared, microwave, X-ray, and gamma rays.

Fluorescence

The conversion of light by a substance and its re-emission as visible light.

Bioluminescence

Light emitted by a living organism.

Translucent

Allows some light to pass through, but not transparent.

Speed of light in a vacuum

3.00 x 10^8 m/s.

Critical Angle

The angle of incidence at which light is totally reflected.

Convex Lens

Causes rays to converge.

Concave Lens

Causes rays to diverge.

Magnification

Magnification can be calculated by dividing image distance by object distance.

Lens Types

Lenses can be converging or diverging.

Focal Power

The power of a lens to converge or diverge light.

Microscopes

Used to visualize small objects at high magnification.
