We witnessed this unique phenomenon over Dull Lake, Srinagar, Kashmir recently while approaching Char Chinar (4 Maples Isle) by shikara (boat). The entire water surface of almost 100 meters x 100 meters was showing us VIBGYOR in horizontal axis.......no true rainbow. I would like you to explain this strange phenomenon....!!!!!!!!

1. Sunlight is composed of light of varying wavelengths. Whilst the shorter wavelength light appears as blue, violet and indigo in color, the longer wavelength light appears as red, orange and yellow in color. When this sunlight passes through a raindrop in the air, it takes a complicated path. Initially light splits into the 'VIBGYOR' colors. This light then reflects off the back surface of the raindrop and then goes back to the other side in which the light first passed, forming an arch. The light thus emerging from several of the raindrops create a rainbow.

2. It is not always that every time it rains we can witness this colorful rainbow in the sky. The prerequisite for rainbow formation is a brightly shining sun from one side and rain coming from the other direction. When you look at a rainbow, you would see that the sun is behind you. There is a fixed critical angle where the light from the sun is reflected back to you. If there is a water droplet in the right place and at the time of ...more

There is a fixed critical angle where the light from the sun is reflected back to you. If there is a water droplet in the right place and at the time of a rain, there will always be raindrops in the right place because drops falling behind will replace the earlier ones. A rainbow with the brightest colors is seen when the sun is quite low on a clear sky just behind us, and a heavy rain just in front of us.

BUT WHAT WAS THIS?????

Hi Subhash

I am pretty sure that light is stiking the lake at a lowish angle from a direction outside the frame - the light is then refracting through the low mist/haze on the lake. Light smoke from wood fires would also cause this.

Hi,
A minimalist composition, yet very beautiful. The strange rainbow like light in the water is a rare occasion and your were there to witness and capture it. Photo quality maybe a little bit week, but a very worthy effort and very enjoyable image. I like it. thanks.

Dear Subhash,
I have added your work to my theme "Nature's oddities,
Thanks for sharing
Kind Regards
Ingrid
