the equator
When the northern hemisphere is in winter, the southern hemisphere is in summer.
It is because the vertical rays covers the larger surface area where as the slanting rays does not.
The tangent ray refers to either the northernmost or southernmost hemisphere where the vertical rays refers to direct sun. During the June 21 solstice, the latitude rays in the southern hemisphere would be 66.5 deg S (Antarctic Circle)
Srinagar (India)
In India, the city of Kanyakumari never gets the vertical rays of the sun due to its geographical location at the southernmost tip of the Indian subcontinent. This unique phenomenon allows visitors to witness both the sunrise and sunset over the sea from the same location.
The sun's rays are never vertical towards the Arctic Circle due to the tilt of the Earth's axis, which is approximately 23.5 degrees. This axial tilt causes the sun to follow a lower angle in the sky during the winter months, preventing direct vertical sunlight. As a result, areas within the Arctic Circle experience prolonged periods of low-angle sunlight in winter and continuous daylight in summer, but the sun never reaches a vertical position at noon.
Cities located near or above the Arctic Circle, such as Longyearbyen in Svalbard, Norway, do not receive vertical rays of the sun due to the angle of the Earth's tilt. This phenomenon occurs during the polar night in winter when the sun remains below the horizon for an extended period.

The northern hemisphere is exposed to vertical rays of the sun during the summer solstice, which occurs around June 21st. This is when the North Pole is tilted towards the sun, leading to longer daylight hours and more direct sunlight in the northern hemisphere.
the equator
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.
Obviously the angle of incidence is different. The oblique rays spread their energy over a larger area of the surface than vertical (also called perpendicular or normal rays)
The latitude where the vertical direct rays of the sun occur is the Tropic of Cancer at approximately 23.5 degrees North. This happens during the summer solstice in the Northern Hemisphere around June 21st each year.
When the Earth is in position M, which typically corresponds to the summer solstice in the Northern Hemisphere (around June 21), the latitude that receives the vertical rays of the sun is 23.5° N, known as the Tropic of Cancer. Conversely, during the winter solstice (around December 21), the vertical rays hit 23.5° S, or the Tropic of Capricorn. During equinoxes, the sun's rays are directly overhead at the equator (0° latitude).
