Atoms - Result Question 35

37. Which of the following transitions in a hydrogen atom emits the photon of highest frequency?

[2000]

(a) $n = 2$ to $n = 1$

(b) $n = 2$ to $n = 6$

(d) $n = 1$ to $n = 2$

Show Answer

Answer:

Correct Answer: 37. (a)

Solution:

(a) $\bar{v} = R [\frac{1}{n_{1}^{2}} - \frac{1}{n_{2}^{2}}]$ or $\frac{1}{λ} = R [\frac{1}{n_{1}^{2}} - \frac{1}{n_{2}^{2}}]$

Frequency, $v = R c [\frac{1}{n_{1}^{2}} - \frac{1}{n_{2}^{2}}]$

Note: See the greatest energy difference and also see that the transition is from higher to lower energy level. Hence, it is highest in case of $n = 2$ to $n = 1$ .
