Given that the refractive index of air is 1.0 and the refractive index of glass is 1.5, what is the angle of refraction?
A) \[\text{22}.\text{6}{}^\circ \]
B) \[\text{3}0.\text{8}{}^\circ \]
C) \[\text{35}.\text{3}{}^\circ \]
D) \[\text{4}0.0{}^\circ \]
Correct Answer: C
Solution :
As per the given figure on page 11, \[{{n}_{i}}\sin i={{n}_{r}}\sin r,(1)\sin (i){{60}^{o}}=(1.5)\sin (r)\] \[=1\times \frac{\sqrt{3}}{2}=1.5\times sin(r),\] \[\text{sin r}=\text{ }0.\text{577},\text{ r}=\text{ 35}.\text{3}{}^\circ \]
