Question

Energy levels, A, B, C, of a certain atom correspond to
increasing values of energy i.e., EA < EB < EC. If ????₁, ????₂, ????₃
are the wave lengths of radiations corresponding to the
transition from C to B, B to A and C to A respectively,
which of the following statements is correct ?
(a) ????₃ = ????₁ + ????₂ (b) ????₃ = ????₁????₂/????₁+????₂
(c) ????₁ + ????₂ + ????₃ = 0 (d) ????₃² = ????₁² + ????₂²

Answer 1

Explanation:

the wave lengths of radiations corresponding to the

transition from C to B, B to A and C to A respectively are as f6

Answer 2

If energy levels, A, B, C, of a certain atom correspond to increasing values of energy i.e., EA < EB < EC and ????₁, ????₂, ????₃

are the wave lengths of radiation corresponding to the transition from C to B, B to A and C to A respectively, then among the statements, (b) is correct.

This is explained as follows:

1. For increasing values of energy wavelenth decreases.

2. Hence ????₁ >????₂ > ????₃.

3. From the options, we can conclude that

(a) ????₃ = ????₁ + ????₂ os wrong as ????₃ is not the greatest.

(b) ????₃ = ????₁????₂/????₁+????₂ may be correct as it is satisfied for wavelength values 3, 2 and 1 respectively.

(c) ????₁ + ????₂ + ????₃ = 0 is also wrong as sum of energies is never zero.

(d) ????₃² = ????₁² + ????₂² is wrong as well as ????₃ is not the greatest.
