WAVE PROPERTIES AND THE ELECTROMAGNETIC SPECTRUM
FOR YOUR NOTEBOOK:
Lesson 1: Electromagnetic Spectrum
Key Terms:
Electromagnetic Radiation - Transverse wave that transfers both electrical and magnetic energy. (Doesn't require a MEDIUM)
Medium - matter that energy can travel through.
Transverse wave - wave that has perpendicular shaping in comparison to the motion of the wave.
Origin - where the energy wave came from
Crest - A peak in a transverse wave.
Trough - A dip in a transverse wave.
Amplitude - the distance from the origin line of the wave to a crest or trough
With radiation it's "Intensity"
Wavelength - the distance between two corresponding parts of a wave.
Ex. Distance from 1 crest to the next crest
Frequency - The number of complete waves that pass a given point in a given amount of time.
Electromagnetic Spectrum - The entire organized diagram of different types of electromagnetic waves.
Shows that higher energy means higher frequency
Spectrum Features:
Gamma Rays
X Ray
Ultraviolet
Visible Light - ROYGBIV
Infrared
