## anonymous 3 years ago On a sunny day, sunrays which propagate in the water make an angle of 50◦ with the water surface. How high (in degrees) is the Sun above the horizon?

Use Snell's Law. The refractive index between one medium and another is:$\frac{\sin I}{\sin R}$ |dw:1353514675528:dw|The refractive index of water to air is about 1.33
