Watching The Sun Set.

So, here in England the Sun has been beaming down on us a lot these past few days.
On these lovely warm evenings it’s incredibly tempting to go out on a romantic stroll to watch the Sun set.

But in which one of these beautiful images has the Sun actually ‘set’ in?

A)

B)

C)

Well the correct answer is B.
Why?
Because although it appears above the horizon, it actually falls below it when the lower edge of the Sun appears to hit it.
The light of the Sun passes through the horizon at a decreasing angle, this bends the light increasingly as there becomes a greater amount air it has to pass through.
It’s a coincidence that the degree of light bending is almost equal to the Sun’s diameter.
