- 1LightA form of electromagnetic radiation
- 2Electromagnetic RadiationA type of energy composed of 2 perpendicular oscillating WAVES:
-Electric field (electrical particle exp a force)
-Magnetic force (magnetized particular exp a force) - 3How does all the electromagnetic waves move? This is called?They move through space
at the SAME CONSTANT speed.
= called speed of light (3.00 × 10^8 m/s) - 4Wavelength -definition and symbolThe distance between 2 waves measured by identical points in each wave (either each crest, trough, or alternate nodes)
- 5Amplitude definitionThe height of the wave (distance from node to crest or node to trough)
- 6What is amplitude a measure of? What happens when the amplitude gets larger?It is a measure of light intensity
The larger the amplitude, the brighter the light. - 7Frequency definitionthe number of cycles (or wave crests) that pass through a stationary point in a given period of time.
- 8What are the units for frequency?The units are
-cycles per second: s^-1 (or cycle/s).
Or hertz (Hz), defined as 1 cycle/s.
