The sun is directly overhead on the Tropic of Cancer at the time
of the June solstice ... roughly June 21 or 22.
The tropics, which are the area between the Tropic of Cancer at 23 degrees 26 minutes north and the Tropic of Capricorn at 23 26S.
The direct rays of the sun reach their northernmost point at the Tropic of Cancer, located at approximately 23.5 degrees north latitude, during the summer solstice. Conversely, they reach their southernmost point at the Tropic of Capricorn, around 23.5 degrees south latitude, during the winter solstice. Between these two tropics, the sun's rays are direct at noon during the corresponding solstices.
tropic of cancer
You must mean: "When the tropic of Cancer recieves the rays of the sun at a 90 degrees angle". We call that the Equinox.
Most of Latin America lies within the Tropics- the area between the Tropic of Cancer and the Tropic of Capricorn. This area has generally warm temperatures because it receives the direct rays of the sun for much of the year. Yet even within the Tropics, mountain ranges and wind patterns create a variety of climates in the region.
It is called the Tropic of Cancer.
Rays Between The Tropic Of Cancer And The Tropic Of Capricorn. - Mariah Dominic
The location on Earth that most often receives rays from the sun at a direct overhead angle is the Equator. This region experiences direct sunlight at noon during the equinoxes, around March 21 and September 23, when the sun is positioned directly above the equator. Additionally, areas within the Tropics—specifically between the Tropic of Cancer and the Tropic of Capricorn—can also experience the sun directly overhead at different times of the year.
In the tropics, near the equator, the sun's rays strike the Earth's surface at nearly a 90-degree angle, resulting in more direct and concentrated sunlight. This is why these regions receive more solar energy and experience higher temperatures compared to regions farther from the equator.
The tropic of Cancer is 23° North of the Equator. It represents the point where the Sun can be directly overhead. If you are any further north, the Sun can not be overhead. The corresponding feature in the southern hemisphere is the Tropic of Capricorn. As to the Sun's direct rays, they can be anywhere from the South Pole to the North Pole. Those two points and everything in between receives the Sun's direct rays at some time during the year.
During the vernal equinox, the sun's most direct rays travel approximately 0.5 degrees of latitude per day. This is because the sun moves across the celestial sphere at a rate of about 1 degree per day, and since the Earth is tilted at about 23.5 degrees, the direct rays shift between the Tropic of Cancer and the Tropic of Capricorn throughout the year. On the equinoxes, the sun is directly overhead at the equator, marking the transition of direct sunlight between the two tropics.
The sun is strongest at the equator because of its direct angle, resulting in more intense solar radiation. The most direct sunlight on Earth occurs in the tropics, where the sun's rays hit the Earth's surface more vertically compared to higher latitudes.
