Of the following transitions in hydrogen atom, the one which gives emission line of minimum frequency is -
Text Solution
Verified by ExpertsThe correct answer is:
C
For emission, the electron must move from a higher level to a lower level.
So valid options are: 
and 
.
Frequency of emitted radiation is proportional to energy difference:
Now compare:
For 
:
For 
:
Clearly,
Since frequency 
energy, smaller energy → smaller frequency.
Correct answer:
