When light passes through a concave mirror lights are deflected and form any colour because light consist of 7 colour. After rainfall there are water vapour in the sky those are worked as concave lens. When sunlight passes through the water vapour lights deflect and shows 7 colour. We see many colour from a bubble because of the reason.
You see a rainbow in the sky because of the interaction of sunlight with water droplets in the air. When sunlight passes through the water droplets, it is refracted (bent) and dispersed, creating the different colors of the rainbow.
In the sky
If it is sunny after the rain has stopped, you are likely to see a rainbow in the sky.
We see a ainbow in the sky when this happens
Noah saw in the sky the first rainbow.
There are many people who believe that a rainbow is indeed a beautiful thing to see in the sky. These people enjoy simple color.
The rainbow is almost always in the day sky, produced by sunlight. Very rarely, one can appear in the night sky, produced by moonlight.
Because in order to see a rainbow, the sun must be in a clear patch of sky.
Rainbow is due to dispersion of light as it reflects from rain drops. Red sunset and blue sky are due to Rayleigh's scattering.
raindrops or clouds p.s. after you might see a rainbow
A rainbow is a circle. What we see from almost any point on earth is a semicircle, or just a part of the rainbow. We can only see it from horizon to horizon, or just an arc of the whole rainbow. Occasionally we can see a full circle of a rainbow in the sky surrounding the sun, and sometimes multiple ones.
In order to see a rainbow, you must have the sun behind you in clear sky, and rain or heavy mist in the air in front of you. If it's raining on you, then most likely the sun is not in clear sky behind you, and you can't see very far in front of you.
A rainbow is formed when sunlight passes through a water droplet and refracts into the entire colour spectrum. You can see a rainbow when it is cloudy because there are far more water droplets in the sky, and therefore more chances that you will see a rainbow. Rainbows, however , are far more common during a sun shower, as there is more unreflected light in the sky
