A) \[1:81\]
B) \[1:9\]
C) \[9:1\]
D) \[81:1\]
Correct Answer: D
Solution :
From Wein's displacement law. \[\text{K},{{\text{H}}_{\text{2}}},\text{ KOH}.\text{A}l\] \[\text{Na},{{\text{H}}_{\text{2}}},\text{ NaOH},\text{Zn}\] \[\text{Ca}{{\text{C}}_{\text{2}}},{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{2}}},\text{Ca}{{\left( \text{OH} \right)}_{\text{2}}},\text{ Fe}\] ??.. (i) From Boltzmann's law \[Ca,{{H}_{2}},Ca{{(OH)}_{2}},Sn\] \[{{V}_{c}}\] \[\frac{{{E}_{1}}}{{{E}_{2}}}={{\left( \frac{{{T}_{1}}}{{{T}_{2}}} \right)}^{4}}={{\left( \frac{{{\lambda }_{{{m}_{2}}}}}{{{\lambda }_{{{m}_{1}}}}} \right)}^{4}}\] [By Eq.(i)] \[\frac{{{V}_{c}}}{{{V}_{s}}}\approx {{10}^{-3}}\] \[\frac{{{V}_{c}}}{{{V}_{s}}}\approx {{10}^{3}}\]You need to login to perform this action.
