Do I see waves coming? Maxwell’s equations predict E -M waves Maxwell’s equations result in two perpendicularly oscillating waves propagating simultaneously in the same direction Velocity

Fronts and Magnitudes There is a relation between E and B The ratio of the magnitudes of the fields gives the velocity of the wave z x B(t) E(t) Visualize crests moving outwards called wave fronts
