At the end of every rainbow, you will not find any physical object or tangible entity. Rainbows are optical phenomena that occur when sunlight is refracted, reflected, and dispersed by water droplets in the air, creating a spectrum of colors. The appearance of a rainbow varies depending on the observer's position and the angle of sunlight.
Due to their optical nature, rainbows are intangible and elusive. They are formed by the interaction of light and water droplets, resulting in a beautiful arc of colors in the sky. While you may see the end of a rainbow, you won't find any specific object or treasure awaiting you there. The notion of a pot of gold at the end of the rainbow is purely a legend and a popular cultural belief rather than a factual reality.
