Light shafts are a type of natural phenomenon that occurs when sunlight passes through openings in the clouds and illuminates the ground below. The term 'light shafts' is derived from the word 'RAYS, ' which is a four-letter word used to describe the beams of light that are created. Light shafts can be seen in many places, such as forests, deserts, and other areas with open skies. They can also be seen in photographs and paintings, providing a beautiful and unique effect.
