Formation of Rainbow

Rainbow is a beautiful and colorful phenomenon that occurs in nature. It is formed when sunlight passes through raindrops in the atmosphere. The formation of a rainbow can be explained by the following steps:

Step 1: Sunlight Enters the Raindrop

Sunlight is made up of different colors of light that have different wavelengths. When sunlight enters a raindrop, it slows down and bends or refracts. This causes the different colors of light to spread out or disperse.

Step 2: Light is Reflected Inside the Raindrop

After the light is refracted, it is reflected off the inside of the raindrop. This causes the light to bounce back towards the front of the raindrop.

Step 3: Light is Refracted Again

Once the light is reflected, it is refracted again as it leaves the raindrop. This causes the different colors of light to spread out even more.

Step 4: Rainbow is Formed

When the refracted light leaves the raindrop, it creates a spectrum of colors that we see as a rainbow. The colors are always in the same order: red, orange, yellow, green, blue, indigo, and violet.

Conclusion

In conclusion, the formation of a rainbow is a beautiful and natural phenomenon that occurs when sunlight passes through raindrops in the atmosphere. It is a complex process that involves the refraction and reflection of light. The result is a spectrum of colors that we see as a rainbow.
