Photons travelling through space at the speed of light, c = 3x10^8 m/s 2. Oscillating electric and magnetic fields that resemble a sine curve a) Amplitude is the vertical height of a crest of depth of a trough from the x axis (1) Determines intensity/brightness- greater amplitude = greater intensity b) Wavelength is the distance between two crests (1) Symbol λ (2) Determines color
