A.It is less than the energy of the photon.
B.It is about one third the energy of the photon.
C.It is exactly half of the energy of the photon.
D.It is equal to the energy of the photon.
E.It is exactly twice the energy of the photon.
B.It is about one third the energy of the photon.
C.It is exactly half of the energy of the photon.
D.It is equal to the energy of the photon.
E.It is exactly twice the energy of the photon.
-
D. Equal to the photon energy.
-
the energy level can take two electrons so It is exactly twice the energy of the photon.
