2 Waves (cont) - Wavelength λ (Lambda): The distance between corresponding points on adjacent waves. -Amplitude: The vertical distance from the midline of a wave to to the peak. Electromagnetic Radiation D e f i n i t i o n : Electromagnetic radiation is the emission and transmission of energy in the form of electromagnetic waves. All electromagnetic radiation travels at the same velocity: the speed of light ( c ). c = 3.00 × 10 8 m/s. c = λν wavelength: SI unit: m, cm, nm frequency: SI unit Hz or /s 4
