  1. everyday life - Why do sunbeams diverge even though the sun is …

    Dec 26, 2014 · The same applies to the beams of light above them. The Sun is very far away and the beams are pretty much parallel, but they're pointing towards you, and perspective makes them appear to converge towards the vanishing point - which in this case is the Sun's location in the sky. The technical term for these beams is "crepuscular rays."

  2. 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.

  3. How is distance between sun and earth calculated?

    Feb 15, 2011 · 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 ;-).

  4. How does the Earth's orbit change as the Sun decreases in mass?

    Mar 10, 2020 · Now the Sun loses a small amount of mass. The Earth is still traveling at the same velocity, and requires the same centripetal force to maintain the same circular orbit. Unfortunately, the reduced mass of the Sun no longer supplies the required centripetal force. So the Earth is now in a slightly elliptical orbit, passing perihelion.

  5. What makes Sun's light travel as parallel beams towards earth?

    Dec 28, 2014 · Light from the sun actually converges on the earth - the sun is about 220 Earths across, so light from one edge and light from the other edge must converge to reach the same point on Earth. The angle is small enough (about 0.5 degrees) that for most practical purposes we can consider the sun to be either a point source or a uniform flat source ...

  7. How can sunlight be white , but pictures of the sun be orange?

    The Sun is white, but the reason why it is white is because your brain adjusts the white balance to make the totality of all the ambient light illuminating the objects you see, white. Now, the Sun is too bright to look directly at safely, but around dusk or dawn you can sometimes see by accident a glimpse of it, and it then looks red.

  8. Why do we say that the Earth moves around the Sun?

    In the case of the two-body system things are quite simple. The shape of Earth trajectory as seen from Sun or that of Sun as seen from Earth are the same. In addition, since the center of mass of the Sun-Earth system is within Sun, Earth trajectory as seen from Sun is almost coinciding with the same orbit as described from the center of mass.

  9. Why does the Sun appear larger during the sunrise and sunset?

    Jul 22, 2017 · $\begingroup$ Just one addition: I think it may also be plausible that due to the sun rising, the atmospheric scattering does not disperse as much light, so that the sun's corona is highly contrasted against everything. What you may get then, is something like an overexposed photography, where light sources shining directly into the lens appear ...

  10. Moon vs Sun size and distance 400 times - Physics Stack Exchange

    Jan 16, 2017 · The Sun and Moon seem to have the same size because of this amazing coincidence: the moon is 400 times smaller than the Sun and 400 closer than the Sun. Checking 400 from this source: The Moon's distance from the Earth: 384,000 km and diameter: 3,480 km The Sun's distance from the Earth: 149,000,000 km and diameter of 1,392,000 km
