Electromagnetic Spectrum 1 Electromagnetic Spectrum - transverse wave - does not require a medium - v = fλ v = 3.0 x 10 8 m/s (in air/vacuum) - f & λ determines EM wave, color, etc. - composed of vibrating electric & magnetic fields that regenerate each other. Electromagnetic Spectrum - all travel@same rate – speed of light 300,000,000 m/s.
