Most Important Selected Qs for JEE AdvancedPhysicsAtomic Physics
In the hydrogen atom spectrum _ 3-1 and _ 2-1 represent wavelengths emitted due to transition from second and first excited states to the ground state respectively. The value of _ 3-1 _ 2-1 is
Options
- A27 / 32
- B32 / 27
- C4 / 9
- D9 / 4
Correct answer
A. 27 / 32
Step-by-step solution
aligned & 1 _ 3-1 = R ( 1 1^2 - 1 3^2 )= 8 R 9 & 1 _ 2-1 = R ( 1 1^2 - 1 2^2 )= 3 R 4 & _ 3-1 _ 2-1 = 27 32 aligned
