• A)The metal atoms absorb the light into their nucleus.
• B)The free electrons in the metal capture the light.
• C)The electric field of the wave excites electrons,which move through the solid conductor and dissipate the electric field,stopping the light wave.
• D)The magnetic field polarizes iron,so all metals have a similar property,so when the magnetic field interacts with atoms,it dissipates the wave.
