A normal rainbow follows the 'laws' strictly. I am looking for some additional factor which would modify the appearance to allow it not to appear circular as with a normal bow.Crystal pendants operate in a totally different way, producing a real image on a surface. If you understand the difference between real and virtual images how can bring that phenomenon into the discussion? If you don't understand, then read about them - it shouldn't compromise any of your principles to find out something like that - and you may see what I am getting at.Let's try some proper Science, for a change.
I'm thinking it has something to do with the light passing through droplets to create two rainbows. Maybe having the light go through the droplets from two sources such as a reflection from one other source has something to do with it? Has the light passing through the droplets been split into two sources?
Karen W. I too experience driving through a rainbow. I was a passenger in a car, driven by by mom. It happened happened about 30 years ago when I was a teenager, but I remember it well, not something easily forgotten and somehow it changes your life forever. It was a double rainbow and it covered our two-lane road like a canopy or covered bridge and went on for several blocks. it was simply, indescribably amazing and we were both in profound and utter awe. I remember wondering while it was happening if other people were seeing it too, or if it was just us. Years later, my mother described it as like "traveling through another dimension." And I couldn't have put it better. That is exactly what it felt like. B.
I have also experienced driving through a rainbow. I was with my husband about 20 yrs ago driving in the Redwoods in California, U.S.. The road was very curvy and the canopy above from the trees was almost complete. Once in a while a break in the forest would allow some sun shine through here and there and the rain was mostly a drizzle. Rounding a sharp hairpin turn while climbing up the mountain road the sun on the dusty windshield made it nearly impossible to see the road for a second, but as we began turn we were suddenly bathed in a spectrum of light. We were driving very slowly on this slippery mountain road. I turned to my husband,to see if he saw the same thing,my husband was focused on the road but I saw him smiling. Then we were through it. It was probably only a few seconds of time but it seemed in slowed motion. It was very cool and I will never forget the feeling of amazement and warmth that we shared that day. When we got to the campground, next to the Pacific Ocean our friends began to tell us about this, "very brillantly colored rainbow that went right down into the trees." They could see it from the beach.To those who do not believe-Scientifically the spectrum can be seen when light shines through a transparent medium (like a raindrop) and undergoes partial internal reflection, and this is refracted between the angles of 40°(violet) and 42°(red). The rest of the colors fall in between. Physics tells us we can never find the end of the rainbow because if we see the rainbow we are already at the proper angle and if we move the angle will change. BUT...physics does not say that a rainbow cannot find us. (Not us personally of course). There is really no reason why, albeit the odds have got to be phenomenal, that if all the conditions were right it is possible. There are rainbows present that we don't see because our angle is wrong between the drops and the sun, so depending on where the sun is in the sky a rainbow could be anywhere.I also want to say that I am thrilled to find this site and others who have experienced this, I knew what we saw that day was real, I just never met anyone else who experienced it too.
