Question

Which of the following transitions in a hydrogen atom emits the photons of highest frequency?

• A. n=1 to n=3
• B. n=2 to n=6
• C. n=1 to n=2
• D. n=3 to n=1

Answer 1

The correct option is B n=2 to n=6

$\begin{array}{c}\text{we know}\\ \text{Energy = h v}\\ \text{where h= plank constant}\\ v=\text{frequency}\\ \text{so, greater enegy higher will be frequency.}\end{array}$

$\begin{array}{c}\text{Energy released during transition in hydrogen}\\ E=+13.6(\frac{1}{n_1^2}-\frac{1}{n_2^2})\end{array}$

$\begin{array}{c}\text{So, maximum Energy released is}\\ \text{from}n=2\text{to}n=6\end{array}$
