How much lux does the Sun emit? - Physics Stack Exchange When you look 'at the world' (i e to the horizon) on a clear day, unlesss the sun is at a very low angle, the surface of your eye is not illuminated directly by the sun, only reflected sunlight from the atmosphere, ground and objects The 32,000-100,000 lux figure is referring to a horizontal surface illuminated directly by the sun
What is the simplest way to prove that Earth orbits the Sun? If we assume the Sun orbits the Earth, the math says that the Sun should be much less massive than the Earth If we assume the Earth orbits the Sun, the opposite is true Either way we can get an estimate of the mass of the Sun We know from other tests that the Sun is more massive than the Earth, so therefore the Earth orbits the Sun

How is distance between sun and earth calculated? Another way of calculating the earth - sun distance is to look at the centrifugal and the gravitational force This solution assumes that one already knows the mass of the sun, but thats a different problem ;-)
Why does sunlight have low entropy? - Physics Stack Exchange At the sun's surface, sunlight is similar to black body radiation at the sun's surface temperature Thus, if you brought a surface next to the sun's surface, it would be able to heat up to that same temperature And this temperature determines the entropy content of the sunlight Now the sunlight leaves the sun and spreads out through space
What is actually meant by sun set and sun rise times, when taking . . . The Sun has actually set risen and we see it due to the way light is bent across the atmosphere Apparently due to coincidence of the size and distance of the sun, its exactly the same size - so if we see 50% of the sun, the sun is 50% below the horizon So, I understand all this, so here is my question :
How hot can metal get in sunlight? - Physics Stack Exchange If the building is located in Hammerfest, Norway the metal might get warm to the touch If it's on the sun-facing side in Las Vegas you may find it gets hot enough to cause burns A definitive answer is not possible If people can touch it easily the temperature is a concern If it's out of reach, don't worry about it The iron isn't going to melt
optics - Why does sunset over a body of water cause a path of light . . . When the sun is very low on the horizon the amount of angular deflection needed to redirect the light to your eye is very small All of the tiny little waves caused by wind on the surface of the sea provide a seemingly continuous path to the sun This is also the reason that the track to the sun is significantly broader than the sun itself
sun - Why is sunlight spectrum continuous? - Physics Stack Exchange The continuous spectrum of the visible photosphere of the Sun is attributable to the radiative equilibrium of the $\mathrm{H}^{-}$ ion This has been recognised for at least 80 years ( Wildt 1939 ) This ion forms by the attachment of a free electron (with a continuous spectrum of energies) to a hydrogen atom, emitting a continuous spectrum of
Why is the solar noon time different every day? Another is the fact that true Sun's path, the ecliptic, makes a $23 5^\circ$ angle with the celestial equator, which also causes seasonal variations in true Sun's speed along the celestial equator To get around these problems, astronomers invented the "mean Sun" for timekeeping, and it moves at a uniform rate (not a variable rate) along the
