- 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
- astronomy - How big a coincidence is the Sun and Moon having almost . . .
It's consensus that the very similar apparent sizes of the Moon and the Sun as seen from Earth is a coincidence (as already answered in this site) This provides us with almost exact total solar
- sun - Why is sunlight spectrum continuous? - Physics Stack Exchange
The sun's spectrum is very complex, and indeed there are a lot of "lines"—both light and dark (emission and absorption)—amidst a sea of what looks to be continuous frequencies
- Why does the sun appear yellow? - Physics Stack Exchange
The sun, in fact, emits light in all colors, but since yellow is the brightest wavelength from the sun, that is the color we see with our naked eye Now, as a photographer, I was always taught that the light from the sun was brightest in GREEN and that is why green is the color to which our eyes are most sensitive
- Why does the Sun shine brighter some days? [duplicate]
1) The sun seems brighter (more dazzling) if there is more scattering in the atmosphere The sun would actually look very small to us in the sky if there were no atmosphere (it's the same angular size as the moon) and most of the brightness seen in the direction of the sun is from small deflection rayleigh scattering
- 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 ;-)
- How long until the sun cannot sustain human life on earth?
The sun will last, at its current brightness for 9 billion more years How long until the sun gets burned down to the point where it cannot sustain life on Earth anymore? Updated: I am more concer
- What is actually meant by sun set and sun rise times, when taking . . .
If this is the case, then when we read things like what time sun sets and rises on websites, books, calendars, other official times, et al… does that mean when we see for example ‘sun set at 18:35’ is the time denoting the actual sun set taking into account of the mirage or what is visible to us
