Question
If h = Planck's constant, the frequency of light emitted when an atom makes a transition is equal to
the energy of revolution of the electron in its lowest energy orbit divided by h.
the energy lost by the electron divided by h.
the energy gained by the electron divided by h.
the energy of revolution of the electron in its highest energy orbit divided by h.
a.the energy of revolution of the electron in its lowest energy orbit divided by h.
b.the energy lost by the electron divided by h.
c.the energy gained by the electron divided by h.
d.the energy of revolution of the electron in its highest energy orbit divided by h.
Explanation / Answer
Ans(c) the energy gained by the electron divided by h.
Its a well known relation,
E = h f => f = E / h
Where, h is Plank's constant, F is frequency and E is the Energy.
When an atom is exited it makes a transition to the heigher state. In an excited state, there is a gain of energy by an atom and it gets transited to higer levels.
(More precisely E is the energy diffrence in intial and final atomic state)
