Question

how are rainbooooooooooows formed

Answer 1

Hi Friend,

Here is your answer,

The sun plays an important part in rainbows. The sun shines through the water particles and the water particles act like prisms. A prism is an object that is transparent, or see-through, and when white light passes through it, it gets 'bent' or spread out into a bunch of different colors. Look at the pictures of prisms. When white light (that contains all of the colors) gets bent or spread out by a prism, you can see the colors separated out from the white light. The raindrops work like prisms to bend the light. Then, you can see a rainbow.

As the sun shines through the water particles, a rainbow is created and you can see it from where you are standing.

The color of the rainbow is:-

Red

Orange

Yellow

Green

Blue

Indigo

Violet

Hope it helps you!

Answer 2

When sunlight encounters a raindrop, part of the light is reflected and the rest enters the raindrop. The light is refracted at the surface of the raindrop. When this light hits the back of the raindrop, some of it is reflected off the back. When the internally reflected light reaches the surface again, once more some is internally reflected and some is refracted as it exits the drop. (The light that reflects off the drop, exits from the back, or continues to bounce around inside the drop after the second encounter with the surface, is not relevant to the formation of the primary rainbow.) The overall effect is that part of the incoming light is reflected back over the range of 0° to 42°, with the most intense light at 42°. This angle is independent of the size of the drop, but does depend on its refractive index. Seawater has a higher refractive index than rain water, so the radius of a "rainbow" in sea spray is smaller than a true rainbow. This is visible to the naked eye by a misalignment of these bows.
