2019 · 10 Apr · Shift 2 · Q51

JEE MainPhysicsAtoms and NucleiMCQ+4 / −1
In Li+ +, electron in first Bohr orbit is excited to a level by a radiation of wavelength λ\lambdaλ. When the ion gets deexcited to the ground state in all possible ways (including intermediate emissions), a total of six spectral lines are observed. What is the value of λ\lambdaλ? (Given : H = 6.63 × 10–34 Js; c = 3 × 108 ms –1)
