Discuss electromagnetic radiation and EM waves. Define how they are characterized by wavelength and frequency. Introduce how these waves are propagated through space as vibrations and a magnetic field, at right angles to each other. Define axis of propagation. Define and discuss wavelength, frequency, and amplitude. Introduce the formula C (speed of light) = lambda(wavelength) x frequency. Discuss C = 2.99 X 10^8 m/s.
