Light Is an Electromagnetic Wave,meaning an Electric Field and Magnetic

question 51

Multiple Choice

Light is an electromagnetic wave,meaning an electric field and magnetic field travel together,oscillating at specific frequency.All metals are electrical conductors and all metals are also opaque to light.Why might this be,knowing the nature of light waves?

• 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.
