What color is 475 nm wavelength?

Color of 475 nm Wavelength

The wavelength of 475 nanometers (nm) falls within the visible light spectrum, which ranges from approximately 380 nm to 750 nm. Light of a 475 nm wavelength is perceived by the human eye as a shade of blue. This specific wavelength is relatively close to the middle of the spectrum of blue light, which can vary in shade from a deeper blue at shorter wavelengths to a lighter, more cyan-like blue at longer wavelengths closer to 500 nm.

Understanding the Visible Spectrum

The visible spectrum is a portion of the electromagnetic spectrum that can be seen by the human eye. The spectrum is typically divided into the following colors, each with its corresponding range of wavelengths:

• Violet: 380-450 nm
• Blue: 450-495 nm
• Green: 495-570 nm
• Yellow: 570-590 nm
• Orange: 590-620 nm
• Red: 620-750 nm

Within this spectrum, each color transitions smoothly into the next, creating a continuous range of colors visible to the human eye. The perception of color is subjective and can vary slightly from person to person.

Significance of Blue Light

Blue light, with wavelengths between 450 nm and 495 nm, is known for its high energy and short wavelength. It is significant for various reasons, including its role in regulating the circadian rhythm, its use in electronic device screens, and its application in optical engineering and photonics. The specific wavelength of 475 nm is often used in applications requiring precise color control and is important in fields such as spectroscopy, optical engineering, and visual arts.
