Question

Energy levels of A , &#160; B , &#160; C of a certain atom correspond to the increasing value of energy, i.e. &#160; E A &#60; E B &#60; E c . If &#955; 1 , &#160; &#955; 2 and &#955; 3 are the wavelengths of radiations corresponding to the transitions C to B , &#160; B to A and C to A respectively, which of the following is correct?

Quantrex Academy · Accepted Answer

Correct answer: B. &#955; 3 = &#955; 1 &#955; 2 &#955; 1 + &#955; 2

Using the diagram given in the question, E C &#8594; A = E C &#8594; B + E B &#8594; A Since, these energies are emitted in the form of photons, E = hc &#955; 1 &#955; 3 = 1 &#955; 1 + 1 &#955; 2 = &#955; 1 + &#955; 2 &#955; 1 &#955; 2 &#955; 3 = &#955; 1 &#955; 2 &#955; 1 + &#955; 2

Energy levels of A ,   B ,   C of a certain atom correspond to the increasing value of energy, i.e.   E A < E B < E c . If λ 1 ,   λ 2 and λ 3 are the wavelengths of radiations corresponding to the transitions C to B ,   B to A and C to A respectively, which of the following is correct?
