Document Summary
Light & eye: a beam of particles, a wave like sound, a wave like radio, a wave with magnetic properties, a wave with electric properties, something magical! A wave like a radio, not like a sound wave. A sound wave needs air to propagate, whereas a light wave does not. It has magnetic and electrical physical properties, nothing magical about it, mostly physical. Electromagnetic radiation a travelling wave of light. Wave is understood as having two main orthogonal components: 1. Magnetic and electric components are oscillating in phase, in different planes. The light we see is only a small part of a large range of energy (electromagnetic radiation). This electromagnetic radiation is described by it"s wavelength, in nanometers. The bit of radiation we are interested in ranges from 400- If you decrease the wavelength (or increase frequency) If you increase the wavelength (or decrease the frequency: you get microwaves, radio, tv, etc.
