Teaching HTET PGT Level 3 - 2024 Mock Test Physics Dual Nature: Photon and Matter Waves The Hydrogen Atom
Hydrogen (1H1), Deuterium (1H2), singly ionised Helium (2He4)+ and double ionised lithium (3Li6)++ all have one electron around the nucleus. Consider an electron transition from n = 2 to n = 1. If the wave lengths of emitted radiation are λ1, λ2, λ3 and λ4 respectively then approximately which one of the following is correct ?
1
λ1 = λ2 = 4λ3 = 9λ4
2
λ1 = 2λ2 = 3λ3 = 4λ4
3
4λ1 = 2λ2 = 2λ3 = λ4
4
λ1 = 2λ2 = 2λ3 = λ4
