Most Important Selected Qs for JEE AdvancedPhysicsAtomic Physics
Hydrogen atoms absorbs radiation of wavelength ₀ and consequently emit radiations of 6 different wavelengths of which three wavelengths are shorter than ₀ .
Options
- AThe final excited state of the atoms is n=4
- BThe initial state of the atoms may be n =2
- CThe initial state of the atoms may be n=3
- DThere are three transitions belonging to Lyman series.
Correct answer
D. There are three transitions belonging to Lyman series.
Step-by-step solution
n(n-1) 2 =6 n=4 If the initial state were n=3 , in the emission spectrum, no wavelengths shorter than ₀ would have occurred. This is possible if initial state were n =2 (A),(B) and (D)
