Question

Energy levels A, B, C of a certain atom correspond to increasing
values of energy i.e., Eᴀ < Eв < Ec. If ????₁, ????₂, ????₃ are the wavelengths of
radiation corresponding to the transitions C to B, B to A and C to A
respectively, which of the following relation is correct?
(a) ????₃ = ????₁ + ????₂ (b) ????₃ = ????₁ ????₂
????₁ + ????₂
(c) ????₁ + ????₂ + ????₃ = 0 (d) ????₃² = ????₁² + ????₂²

Answer 1

Answer:

answer is b

Explanation:

consider E1 from C to B ,E2 from B to A and E3 from C to A . Then u get relation like this

E1+E2=E3

so;

{hc/??1}+{hc/??2}={hc/?3}

=(1/??1)+1/??2=1/??3

solving this u get ;

??3=(??1)(??2)/(??1)+(??2)
