Answer 1

The rays of sunlight that move straight from the sun perpendicular to the surface of the Earth are called **solar radiation** or more specifically **direct solar radiation**. When the sun's rays strike the Earth at a perpendicular angle, they are more concentrated, leading to greater solar intensity in that area. This is typically observed near the equator during midday when the sun is at its highest point in the sky.
