Rainbows are full circles visible from high elevations; they form when sunlight passes through raindrops and refracts and reflects.
Rainbows are a beautiful natural phenomenon that have captivated people for centuries. We often think of them as arches stretching across the sky, but in reality they are full circles. Rainbows are created when sunlight passes through raindrops at the right angle and refracts and reflects the light. This is why only part of the circle is visible to the observer on the ground, as the rest is blocked by the Earth’s surface. The amount of the halo that is visible depends on the angle of the sun and the position of the observer.
The order of colors in a rainbow is determined by the wavelength of the light. Red has the longest visible wavelength and is at the top of the rainbow, while violet has the shortest wavelength and is at the bottom.
To see the entire rainbow circle, you need to be in a higher vantage point such as a plane or tall building. If this isn’t possible, you can try creating a circular rainbow with a garden hose.
Rainbows are a beautiful reminder of the wonders of nature. Although we can’t see the entire circle from the ground, we can still appreciate the beauty of the arch that is visible to us.
