Question 621: Atoms & Nuclei

Question

Energy levels A, B and C of a certain atom corresponding to increasing values of energy i.e. EA < EB < EC.   If $$\lambda $$1, $$\lambda $$2 and $$\lambda $$3 are wavelengths of radioations corresponding to transitions C to B, B to A and C to A respectively, which of the following relations is correct?

Accepted Answer

$$ 	herefore $$ (E
C
Ã¢ÂÂ E
B
) + (E
B
Ã¢ÂÂ E
A
) = (E
C
Ã¢ÂÂ E
A
)
$$ \Rightarrow $$ $${{hc} \over {{\lambda _3}}} = {{hc} \over {{\lambda _1}}} + {{hc} \over {{\lambda _2}}}$$
$$ \Rightarrow $$ $${\lambda _3} = {{{\lambda _1}{\lambda _2}} \over {{\lambda _1} + {\lambda _2}}}$$

Answer

$${\lambda _3} = {\lambda _1} + {\lambda _2}$$

Answer

$${\lambda _3} = {{{\lambda _1}{\lambda _2}} \over {{\lambda _1} + {\lambda _2}}}$$

Answer

$${\lambda _1} + {\lambda _2} + {\lambda _3} = 0$$

Answer

$${\lambda _3}^2 = {\lambda _1}^2 + {\lambda _2}^2$$
