The Sun appears at an angle of 53.0° above the horizontal as viewed by a dolphin swimming underwater. What angle does the sunlight striking the water actually make with the horizon?
The location of sun above the horizon.
Answer to Problem 1PQ
The location of the sun above the horizon is
Explanation of Solution
Write the expression for the angle of incidence on the air-water interface.
Here,
Write the expression to calculate the location of the sun above the horizon.
Here,
Conclusion:
Calculate the angle of refraction of the light rays.
Substitute
Substitute
Therefore, the location of the sun above the horizon is
