Question 579: Atoms & Nuclei

Question

Energy levels A, B and C of a certain atom corresponding to increasing values of energy i.e. E
A
< E
B
< E
C
.   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

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