Question

Which transition correspond to maximum frequency for visible radiation in H-atom?
n 5->n 2
n infty-> n 2
n infty->n 1
n 7-> n 2​

Answer 1

Answer:

Explanation:

for visible radiations with maximum frequency is option b) infinity--->2

Answer 2

The transition corresponding to the maximum frequency of visible radiation is H-atom is n$_{\infinity$$_{\inf}$ to n$_2$.

• We know that the transitions lying in the visible spectrum come under the Balmer series i.e. transitions between n=2 and successive higher states.

• Various transitions are possible to n=2 from higher states, but from Planck's quantum theory, the radiation of maximum frequency corresponds to maximum energy.
• The transition that will give transition of highest energy radiation is from n$_{\infinity$$_{\inf}$ to n$_2$.
• So, the transition corresponding to the maximum frequency of visible radiation is H-atom is n$_{\infinity$$_{\inf}$ to n$_2$.
