The sun is directly over the Tropic of Cancer on the Summer Solstice.
The vertical ray of the sun strikes the Earth directly at the equator. This phenomenon occurs during the equinoxes when the sun is directly above the equator, causing equal day and night lengths at all locations on Earth.

The vertical ray of the sun will strike near the Tropic of Cancer, which is approximately 23.5 degrees north latitude on June 12 at noon. This occurrence is known as the summer solstice in the Northern Hemisphere.
At noon on the vernal equinox, the sun's vertical rays strike the earth along the equator. This is when the lengths of day and night are nearly equal all over the world.

Because the Earth receives vertical rays.
The angle of insolation decreases between solar noon and 6 pm on June 21 in New York State. As the sun moves towards the horizon after solar noon, the angle at which sunlight strikes the Earth's surface becomes more oblique, leading to less intense heating and shorter shadows.
Vertical sunrays refer to sunlight that strikes the Earth's surface at a direct angle, typically when the sun is at its highest point in the sky, such as during noon or at the equator during equinoxes. This phenomenon results in minimal shadow length and more intense solar radiation, often leading to warmer temperatures in those areas. Vertical sunrays are most prominent in tropical regions, where the sun can be directly overhead at certain times of the year.
-The two extremes of angles are on June 21st where the sun is at its highest noon and on December 21st where the sun is at its lowest noon.
33 degrees perpendicular to the horizon
If Earth were smaller but the Alexandria-to-Syene distance remained the same, the angle of the sun's rays would change due to the decreased curvature of the Earth. This would result in a longer shadow cast by a vertical pillar in Alexandria at noon during the summer solstice, as the sun would be positioned lower in the sky compared to a larger Earth. Thus, the shorter radius of the smaller Earth would lead to a longer shadow.
The sun's radiation is most pronounced when it strikes directly overhead, which occurs around solar noon. At this time, the sunlight passes through the least amount of atmosphere, allowing more radiation to reach the Earth's surface.
