Vertical Ray of the Sun

The Vertical Ray of the Sun refers to the sun’s rays hitting the Earth directly overhead at the latitude known as the Tropic of Cancer during the summer solstice (around June 21). This results in the sun being at its highest point in the sky, creating the longest day of the year. At this time, the sun's rays are perpendicular to the surface, causing minimal shadows and maximum solar energy. This phenomenon marks the peak of summer in the northern hemisphere and is a key factor in seasonal changes related to sunlight and temperature.
