* Light is a form of electromagnetic radiation. This radiation comes in a range of wavelengths, and each wavelength corresponds to a different color.
* Our eyes have specialized cells called cones. These cones are sensitive to different wavelengths of light. Some cones are most sensitive to red light, others to green, and others to blue.
* When light enters our eyes, the cones are stimulated. The signals from the cones are sent to the brain, where they are interpreted as colors.
* The combination of the wavelengths of light that reach our eyes determines the color we see. For example, a red object reflects mostly red wavelengths of light, while a blue object reflects mostly blue wavelengths.
How the rainbow forms:
* Sunlight is made up of all the colors of the spectrum. When sunlight passes through water droplets in the air, it is bent (refracted) and separated into its different colors.
* The different colors of light are bent at slightly different angles. This separation is what creates the rainbow.
In essence, the visibility of the VIBGYOR light spectrum is a result of:
* The nature of light itself.
* The way our eyes and brains process light.
* The way light is scattered and bent by water droplets.
So, VIBGYOR is visible because of the physical properties of light and the way we perceive it.
