When it is dawn on one side of Earth, what is happening on the opposite side?
If the question’s phrase “opposite side” means “antipods”, then when it is dawn on one side it is indeed sunset on the other side.
Geometrically, there will be an instant when the horizon (i.e. the plane tangent to the smooth approximation to Earth’s surface) bisects the Sun at the two antipodal points simultaneously. However, because of atmospheric referaction
, there will be a short period before and after that instant when the Sun will be completely visible above the horizon at both points. The amount by which the Sun will be above the horizon around that time can be affected by temperature gradients in the atmosphere near Earth’s surface. On average it will be a bit less than one degree.
This is true even at the poles. There, sunrise and sunset are annual, not daily, events, but the same relationship holds. Within the polar circles, there are periods during which some antipodal points do not experience daily sunrises and sunsets, but when they do, the same relationship holds at antipodal points.
This means that, ignoring atmospheric refraction, when one point is experiencing daylight for a certain period of time per day, the antipodal point is experiencing nighttime for the same period of time per day. The effect of atmospheric refraction is to slightly prolong the daylight at both points.
