Rays of the sun are seen to make a 34.7° angle to the vertical beneath the water. at what angle above the horizon is the sun?

49.19°

Explanation:

θ₁ = Angle of incidence

θ₂ = Angle of refraction = 34.7°

n₁ = Refractive index of air = 1.0003

n₂ = Refractive index of water = 1.33

From Snell's Law

In order to find the angle of sun above horizon we have to subtract the angle

90 - 49.19 = 40.81

The sun is at an angle of 40.81° above the horizon.

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
