Atmospheric Refraction or “Lensing” and Diffusion

“Atmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. This refraction is due to the velocity of light through air, decreasing (the refractive index increases) with increased density. Atmospheric refraction near the ground produces mirages. Such refraction can also raise or lower, or stretch or shorten, the images of distant objects without involving mirages. Turbulent air can make distant objects appear to twinkle or shimmer. The term also applies to the refraction of sound. Atmospheric refraction is considered in measuring the position of both celestial and terrestrial objects.”

“Diffuse reflection is the reflection of light or other waves or particles from a surface such that a ray incident on the surface is scattered at many angles rather than at just one angle as in the case of specular reflection. An ideal diffuse reflecting surface is said to exhibit Lambertian reflection, meaning that there is equal luminance when viewed from all directions lying in the half-space adjacent to the surface.” –Wikipedia

Many things must be considered when considering the APPARENT size of the Sun compared to the ACTUAL size of the Sun. For instance, refraction, which is light bending, as well as diffusion, in addition to perspective and visual acuity, must be considered.

“The reason why light is refracted at a different angle is because light is slowed in velocity as it passes through a medium. Snell's law may be derived from Fermat's principle, which states that the light travels the path which takes the least time. By taking the derivative of the optical path length, the stationary point is found giving the path taken by the light. Therefore, no matter the wavelength or frequency of the light, it will become refracted all the same as it slows in velocity through a medium.

Since the degree of Snell's Law is dependent on wavelength, it just means that some wavelengths are refracted slightly farther than others. The prism experiment would demonstrate nothing, since all wavelengths of light are still affecting much of the sun's spotlight during the course of the day. The only noticeable difference might be at the edge of the spotlight when the sun sets.

And, as we all know, the sun changes to a reddish color at its setting. This is due to the very same quality of Snell's Law you are describing. Red refracts the least, which is a strong indication that refraction is occurring.”

Why Does the Sun Go Down?

“The Sun never sets or rises, it stays the same distance over the Earth throughout its daily/annual journeys around. The appearance of rising and setting is all based on the law of perspective on plane surfaces. The Sun and Moon spotlights are perpetually hovering over and parallel to the surface of the Earth.

From our vantage point, due to the Law of Perspective, the day/night luminaries appear to rise up the Eastern horizon, curve peaking high overhead, and then sink below the Western horizon.
