What Is the Nature of Black in the Visible Spectrum VIBGYOR?

AI Thread Summary
In the visible spectrum VIBGYOR, black is defined as the absence of light, while white represents the combination of all visible colors. Objects perceived as black absorb most incoming light without reflecting it, leading to varying shades of black depending on their reflective properties. The discussion also clarifies that during refraction, the wavelength of light changes while the frequency remains constant, as frequency is a characteristic of the wave source. Additionally, the concept of black holes is touched upon, noting that they can be considered perfect absorbers beyond their event horizon, though perfect absorption does not exist in physical objects. Overall, the conversation emphasizes the relationship between light, color perception, and the physics of waves.

You have to realize that some of the people answering you are probably older than your grandfather and we like the Etiquette of the PF environment.
You never get called a **** or a ***** or even a ****** here. "Demanding" is about the worst thing you can be called and for the member to remain a member :smile:
