Figure shows the enegry 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 obtaned by an energy level change from `Q` so `S`. A blue line can be obtained by following energy level change

A

P to Q

B

Q to P

C

R to S

D

R to G

Text Solution

Verified by Experts

The correct Answer is:
D
If E is the energy radiated in transition , then form figure
`" " E_(RtoG)gtE_(Qtos)gtE_(RtoS)gtE_(QtoR)gtE_(PtoQ)`
For obtaining blue line energy radiated should be be more. Hence, correct option is (d)
