A) \[\frac{24\,hR}{25\,m}\]
B) \[\frac{25\,hR}{24\,m}\]
C) \[\frac{25\,m}{24\,h\,R}\]
D) \[\frac{24\,m}{25\,h\,R}\]
Correct Answer: A
Solution :
Here, \[{{E}_{5}}-{{E}_{1}}=\frac{hc}{\lambda }\] |
and \[\frac{R\,hc}{25}-R\,hc=\frac{hc}{\lambda }\] |
\[\frac{24}{25}R\,=\frac{1}{\lambda }\] |
but \[p=\frac{h}{\lambda }\] |
and \[v=\frac{h}{m\lambda }\] |
\[=\frac{24}{25}\frac{Rh}{m}\] |
(m is the mass of the electron, R Rydberg constant and h Planck's constant) |
