Question

Classify each of the following statements as true or false. Light source A has energy as is seen by the electrons emitted from the surface of the magnesium metal, but light source B has no energy. The magnesium metal does not have enough energy to absorb the energy of light source A but does have enough energy to absorb the energy of the light source B. Light source A has enough energy to cause electrons to be emitted from the surface of the magnesium metal, but light source B does not. Light source B has a shorter wavelength than light source A and therefore cannot cause electrons to be emitted from the surface of the magnesium metal.

Light source A has energy as is seen by the electrons emitted from the surface of the magnesium metal, but light
source B has no energy.
The magnesium metal does not have enough energy to absorb the energy of light source A but does have enough
energy to absorb the energy of the light source B.
