    This video is wrong for the simple reason Helio Cosmology demands that the sun's light takes 8.3 minutes to get to us on earth and that calculation is completely omitted here. It also ignores that the sun moves its own diameter (or height) every 4 minutes. As such, at sunrise the actual position of the sun would be more like twice the height of the sun ABOVE the horizon.

    1. Do the rays of light from the sun travel through space as an actual image of the sun... or as non-distinct dispersed light rays? It is the latter of course, but if it was the former... 2. Since light travels in straight lines, why would the mirage image of the sun that traveled 93 million miles to our atmosphere appear to us as the same size we always see the sun, instead of as if we were seeing the sun from 62 miles away (the height of the atmosphere)?

    6:58 sir why is the shift stronger when the object is lower in the sky; the refractive index has to remain constant so if the angle of incidence will increase so will the angle of refraction ?

  • @furiousarpan7473

    @furiousarpan7473

    Жыл бұрын

    If you have studied total internal reflection you might recall that the ray of light was refracting more and more as we increased our angle of incidence and at a particular angle it got refracted as much as it reflected in the same medium, you can relate the same thing over here, the more angle of incidence means the more bending of light so the shift will be more stronger

    Is this really why sailors in the earlier times used to look at the locations of the stars far from the horizon for navigation? Because yeah, I understand that this is how it works. But how could they have understood it? If they did, then they knew that the Earth was round. I thought that the knowledge of Earth being round was not so popular in medieval times.
