Without millions of rain droplets, a rainbow would not occur. If you only had a few rain droplets you would only see a few colors. This is typically why rainbow appear after a rain storm. Each rain droplet has a function in the formation of the rainbow. Sunlight enters the rain droplet at a specific angle and the rain droplet separates the white light into many different colors.

This angle is a fixed measurement between your eye and the sun. What color is refracted depends upon the critical angle, which is the angle the sunlight strikes the back of the rain droplet.

Red light bends the least, exiting the rain droplet at a 42 degree angle, while Violet light bends the most, exiting the rain droplet at a 40 degree angle.

All of the other colors of the rainbow exit the rain droplets at some angle between 40 and 42 degrees, thus making up the colors of the rainbow ROYGBIV, this order never changes. Each rain droplet reflects all colors at a given point and time, but only one color comes back to your eye, requiring million of rain droplets to create a rainbow.

Expertise. Insights. Illumination.

As the rain droplets fall through the sky, the colors of the spectrum being reflected and refracted are constantly changing. Rainbows form a complete circle, however only half is visible. What causes the rainbow to have a circular formation is the way that rain droplets fall. The rain droplets do not fall is flat sheet, however they tend to fall at various distances and speeds.

On some occasions you can see a full circle around a garden hose. The perfect time and place to look for a rainbow you need bright sunlight to your back and rain clouds off in the distance in the direction of your shadow.

If it is later than 4: Other places you may see rainbows formed are fountains, in the ocean as the waves crash against the rock which create a mist in the air, waterfalls, sprinklers and mist from a garden hose.

Always remember to have the sun at your back to see a rainbow, happy rainbow hunting!!!!!!As mentioned earlier, how rainbows form is not at all as glamorous or fantastic as imagined.

Nonetheless, we can always continue to indulge ourselves in fantastical beliefs, as long as we know what the truth is. Share This. Types of Rainbows.

One path of great significance in the discussion of rainbows is the path in which light refracts into the droplet, internally reflects, and then refracts out of the droplet. The diagram at the right depicts such a path. A light ray from the sun enters the droplet with a slight downward trajectory.

These droplets actually form a circular arc. The Formation of Rainbows The process of rainbow formation has been explained in steps for your easy and better comprehension.
