Which color of light corresponds to approximately 450 nm?

The color of light that corresponds to approximately 450 nm is blue. In the visible spectrum, light wavelengths roughly range from 400 nm to 700 nm. The shorter wavelengths, around 400-450 nm, are perceived as blue to violet, while longer wavelengths in the range of 600-700 nm appear red.

At about 450 nm, light falls squarely within the blue region of the spectrum. This wavelength is associated with colors that our eyes interpret as blue, which is significant in various fields including physics and engineering, particularly when considering applications such as optics and light manipulation.

Understanding the visible spectrum is crucial for recognizing how different wavelengths correspond to different colors, which is applicable in many scientific and engineering contexts. For example, knowledge of light wavelengths is essential in designing lighting systems, analyzing materials, and even in biological applications such as photosynthesis where different wavelengths can affect plant growth.
