Nuclear Physics And Radioactivity Question 41
Question: The transition from the state $ n=4 $ to $ n=3 $ in a hydrogen-like atom results in ultraviolet radiation. Infrared radiation will be obtained in the transition [IIT-JEE (Screening) 2001]
Options:
A) $ 2\to 1 $
B) $ 3\to 2 $
C) $ 4\to 2 $
D) $ 5\to 4 $
Show Answer
Answer:
Correct Answer: D
Solution:
As the transition $ n=4 $ and $ n=3 $ , results in UV radiation and infrared radiation involves smaller amounts of energy UV. So we require a transition involving initial values of n greater than 4 e.g. $ 5\to 4 $ .
