Question : 14 of 200

Marks: +1, -0

The reason why metals are so shiny is

their hardness makes them easy to polish
the electric field of the photon is forced to go to zero at the surface of the
metal, generating a wave in the opposite direction
because metals are so hard, photons undergo completely elastic collisions
which gives them an equal and opposite momentum
metals carry a large static charge at their surface that repels the photons
