A) \[{{30}^{o}}\]
B) \[{{60}^{o}}\]
C) \[{{45}^{o}}\]
D) \[{{90}^{o}}\]
Correct Answer: A
Solution :
As, we know that \[\frac{{{H}_{2}}}{{{H}_{1}}}=\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{1}{2}\] \[\frac{{{H}_{2}}}{{{H}_{1}}}=2({{\mu }_{1}}>{{\mu }_{2}})\]For total internal reflection \[2{{H}_{1}}=\frac{1}{\sin C}=2C={{30}^{o}}\]You need to login to perform this action.
