Atoms And Nuclei Question 32
Question: The energy levels P, Q, R, S and G of an atom where G is the ground state. A red line in the emission spectrum of the atom can be obtained by an energy level change from Q to S. A blue line can be obtained by following energy level change [MP PMT 1994]
Options:
A) P to Q
B) Q to R
C) R to S
D) R to G
Show Answer
Answer:
Correct Answer: D
Solution:
If E is the energy radiated in transition then $ {E_{R\to G}}>{E_{Q\to S}}>{E_{R\to S}}>{E_{Q\to R}}>{E_{P\to Q}} $ For getting blue line energy radiated should be maximum $ ( E\propto \frac{1}{\lambda } ) $ . Hence (d) is the correct option.
