the parallel of latitude 23½ degrees south latitude marking the southern limit of Sun's vertical rays
There is no city in India that receives vertical rays of the sun. All receive slanting Actually there is no place on the earth that receives vertical rays of the sun. Some receive horizontal, some receive slanting and some receive very slanting.
All lattitudes from 22.5 degrees North to 22.5 degrees South of the equator receive vertical or direct rays twice every year as the tilted earth circles the sun.
These most vertical rays can occur anywhere between the tropic of cancer and the tropic of capricorn. The tropic of cancer's most vertical rays occur at noon on the summer solstice, and vice versa. There is a well in Cyene, a city in southern egypt, where the sunlight casts no shadow at high noon. Eratosthenes the Greek, a librarian at Alexandria, used this fact to calculate the circumference of the earth.

on the vertical axis
By exposed it to vertical rays of the sun from the spring equinox to the automn equinox.
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)
srinagar
They contain more solar energy!
Because vertical solar rays are less oblique during Sumner and are concentrated over smaller areas

The tropics.
Yes, the opposite rays of vertical angles are always coplanar, so the angles are as well.
