MCQ
In the following transitions, which one has higher frequency
- A$3 -2$
- B$4 -3$
- C$4 -2$
- ✓$3 -1$
✓
Answer
Correct option: D.
$3 -1$
d
(d) $3 -1$ transition has higher energy so it has higher frequency $\left( {\nu = \frac{E}{h}} \right)$
(d) $3 -1$ transition has higher energy so it has higher frequency $\left( {\nu = \frac{E}{h}} \right)$
