... 2. EM radiation are forms of energy which move through space as waves a. Move at speed of light (c) (1). c= 3.00 x 10^8 m/s b. Speed is equal to the frequency times the wavelength c = νλ (1). Freqency (ν) is the number of waves passing a given point in one second, measured in Hz or s^-1 (2). Wavelen ...
