Answer 1

Answer:

EM waves transmit energy by absorption and re-emission of wave energy by the atoms in the medium. The atoms absorb the wave energy, undergo vibrations and pass the energy by re-emission of EM of the same frequency. The optical density of the medium affects the propagation of EM waves.
