| Light consists of tiny particles of energy that travel as waves.
| Light consists of tiny particles.
| Vision results from streamers or filaments emitted by the eye making contact with an object.
| Light is a wave.
| In modern theory, Light has a dual nature; part particle and part wave.
| Radio waves, microwaves, infrared waves, visible light, ultraviolet rays, gamma rays.
| Energy in an Electromagnetic Wave
| Energy is part electric and part magnetic.
| DO NOT Pass through Light
| Infrared and Ultra-violet light do not pass through glass while visible light does.
| Resonance on Glass
| Electron in glass have a natural frequency in ultra-violet range.
| Atmosphere Transparency
| Our atmosphere is transparent to visible light and some infrared, but almost opaque to ultra-violet light.
| Are semi-transparent to ultraviolet.
Observation from the Umbra during a Solar Eclipse
| Brief darkness during the day.
| Observation from the Penumbra during a Solar Eclipse
| A partial eclipse in which the sunlight is dimmed.
| Polarized Object
| Vibrating Electron
| Incandescent bulb, the sun, a candle flame.
| The idea that light consists of tiny particles was first proposed.
| His measurement of discrepancies in the position of Jupiter's moon lo was the first demonstration showing that light travels at a finite speed.
| Receiving Material Response
| When light is incident upon it depends on the frequency of the light and the natural frequency of the electron in the matter/
| Electron's Response
| Are able to respond to the ultra-fast vibration of visible light because the electrons have small enough mass to vibrate fast.
| Structure of glass
| Infrared waves vibrate only the electrons in glass.
| Transparent Materials
| Absorb light energy and re-emit it so that it is passed on to neighboring atoms.
| Opaque Materials
