JEE MAIN - Physics (2022 - 27th June Evening Shift - No. 18)
Given below are two statements :
Statement I : In hydrogen atom, the frequency of radiation emitted when an electron jumps from lower energy orbit (E1) to higher energy orbit (E2), is given as hf = E1 $$-$$ E2
Statement II : The jumping of electron from higher energy orbit (E2) to lower energy orbit (E1) is associated with frequency of radiation given as f = (E2 $$-$$ E1)/h
This condition is Bohr's frequency condition.
In the light of the above statements, choose the correct answer from the options given below :
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.
Explanation
Radiation is not emitted but absorbed when an electron jumps from low energy to high energy.
Also, E2 $$-$$ E1 is the energy of photon
$$\Rightarrow$$ E2 $$-$$ E1 = hf
$$ \Rightarrow f = {{{E_2} - {E_1}} \over h}$$
