Given below are two statements: Statement I: In hydrogen atom, the frequency of radiation emitted when an electron jumps from lower energy orbit ( E 1) to higher energy orbit ( E 2), is given as hf = E 1- E 2. Statement-II: The jumping of electron from higher energy orbit ( E 2) to lower energy orbit ( E 1) is associated with frequency of radiation given as f =( E 2- E 1) / h This condition is Bohr's frequency condition. In the light of the above statements, choose the correct answer from the options given below:

When electron jump from lower to higher energy level, energy absorbed so statement-I incorrect. When electron jump from higher to lower energy level, energy of emitted photon

E = E_{2} - E_{1}

h f = E_{2} - E_{1}

\Rightarrow f = \frac{E _{2} - E _{1}}{h}

so statement-II is correct.

Both statement I and statement II are true.

Both statement I and statement II are false

Statement I is correct but statement II is false

Statement I is incorrect but statement II is true.

When electron jump from lower to higher energy level, energy absorbed so statement-I incorrect. When electron jump from higher to lower energy level, energy of emitted photon E=E2​−E1​ hf=E2​−E1​ ⇒f=hE2​−E1​​ so statement-II is correct.

When electron jump from lower to higher energy level, energy absorbed so statement-I incorrect. When electron jump from higher to lower energy level, energy of emitted photon
$E = E_{2} - E_{1}$
$h f = E_{2} - E_{1}$
$\Rightarrow f = \frac{E _{2} - E _{1}}{h}$
so statement-II is correct.
