- How much lux does the Sun emit? - Physics Stack Exchange
I want to know how much lux the sun emits on a bright day - I don't mean when one stares directly at the sun, but rather when one walks casually outside when the sun is shinning brightly Now the
- optics - If the sea surface were absolutely calm should the Sun . . .
On the other hand, if the water were completely still, with a smooth and horizontal surface, then the sun glitter ribbon would be gone, and you would just see a direct mirror image of the Sun
- sun - Nuclear fusion - Hydrogen isotopes - Physics Stack Exchange
What is the isotope composition of hydrogen atoms in the sun? Are the ratios of protium:deuterium:tritium similar to those we find on earth? What does the nuclear fusion of hydrogen atoms in the sun
- Black and white matters. But why and how? - Physics Stack Exchange
So a metal door in the sun will transfer the heat of the visible spectrum to the interior if painted black, will reflect it back and keep the interior cooler if painted white It is a good reason for painting roofs and walls white in hot countries A white car is also better in hot countries for this reason
- How is distance between sun and earth calculated?
How has the distance between sun and earth been calculated? Also what is the size of the sun?

- How hot can metal get in sunlight? - Physics Stack Exchange
I quite liked this one [archived] describing measurements on cars It shows that things left in the sun can get significantly hotter than the surrounding air (although there are some issues with the method used, the conclusions are mostly valid), One final note - how hot things are is not the same as how hot they seem to be
- Why does the Sun always rise in the East? - Physics Stack Exchange
The Sun does not rise, it is the horizon that goes down You say that Sun rises in the East (with a certain degree of oscillations due to the tilt of the axis) just because the Earth spins from West to East The revolution affects the difference between sidereal time and solar time, and makes the solar day ≈ 4 ≈ 4 minutes longer If the Earth spinned in the opposite direction the Sun would
