Given that the refractive index of air is 1.0 and the refractive index of water is 1.3, what is the angle of incidence?
A) \[\text{22}.\text{6}{}^\circ \]
B) \[\text{23}.\text{1}{}^\circ \]
C) \[\text{39}.0{}^\circ \]
D) \[\text{4}0.\text{5}{}^\circ \]
Correct Answer: A
Solution :
As per the given figure on page 11, \[{{n}_{i}}\sin i={{n}_{r}}sin\,r,(1.3)\sin \,(i)=(1)\sin {{30}^{o}}\] \[\frac{13}{10}\sin i=\frac{1}{2}=0.3846,i={{22.6}^{o}}\]
