Here we need to calculate the angle above the horizon does the person on the shore of lake see the sun. The sun appears at an angle ${\theta{}}_{r}=3{5}^{o}$ from the vertical. Let the incident angle of sun rays on lake surface is ${\theta{}}_{i}$ . The angle above the horizon does the person on the shore of lake see the sun is $90-{\theta{}}_{i}$ . Let the refractive index of the water be ${\eta{}}_{w}=1.33$ and air is ${\eta{}}_{a}=1$ .
