Abeam of light hits a sheet of metal. if it has enough energy, electrons break free from the metal sheet.

which choice correctly describes the behavior of light in this situation?

1. in this situation, light behaves as a particle colliding with another object. this is because increasing the energy in the light beam releases more electrons from the metal, but does not increase the energy carried by each electron.

2. in this situation, light behaves as a particle colliding with another object. this is because increasing the energy in the light beam increases the energy carried by each electron but does not increase the number of electrons released.

3.in this case, light acts like a wave because it requires the total energy of a wave to dislodge the electron. increasing the energy in the light beam releases more electrons and increases the energy carried by each electron.

4.in this case, light acts like a wave because it requires the total energy of a wave to dislodge the electron. increasing the energy in the light beam doesn’t releases any more electrons but it does increase the energy carried by each electron.
