A) [\[M_{{}}^{0}L_{{}}^{0}T_{{}}^{-1}\]]
B) [\[M_{{}}^{0}L_{{}}^{-1}T_{{}}^{-1}\]]
C) [\[M_{{}}^{2}L_{{}}^{{}}T_{{}}^{-3}\]]
D) [\[M_{{}}^{0}L_{{}}^{-1}T_{{}}^{0}\]]
Correct Answer: D
Solution :
[d] In Bohr's model, \[\frac{1}{\lambda }=\frac{m{{e}^{4}}}{{{\varepsilon }_{0}}^{2}{{h}^{3}}c}\left( \frac{1}{{{n}_{1}}^{2}}-\frac{1}{{{n}_{2}}^{2}} \right)\] Where \[\lambda \]=wavelength, \[{{n}_{1}}\]and \[{{n}_{2}}\]are principal quantum numbers. \[\therefore \left[ \frac{m{{e}^{4}}}{{{\varepsilon }_{0}}^{2}{{h}^{3}}c} \right]=[{{L}^{-1}}]=[{{M}^{0}}{{L}^{-1}}{{T}^{0}}]\]You need to login to perform this action.
