No, rainbows do not actually touch the ground.
Why Rainbows Appear to Touch the Ground
Rainbows often seem like they have a definite start and end point on the horizon, which may look like they are touching the ground. However, this is just an optical illusion. The appearance is due to the way that light is refracted and reflected within water droplets, creating the curved arc that we see.
The Circular Nature of Rainbows
The reference explains that rainbows are actually full circles, but we usually only see the top portion because the ground blocks our view.
- If you were high enough above the ground, for example in an airplane or on a mountain top, you would see the rainbow as a complete circle. This is mentioned in the reference as proof that rainbows are not touching the ground.
Rainbows: Not an Actual Physical Object
It is important to understand that rainbows are not physical objects that can be touched. A rainbow is a phenomenon created by light and water droplets and only exists relative to the observer.
