Visible Light Spectrum: Exploring the Colors of the Rainbow

What do the wavelengths of 380-430 nm indicate in the visible light spectrum?

a) Blue
b) Green
c) Violet or Purple
d) Yellow

Answer

The wavelengths of 380-430 nm indicate violet or purple light in the visible light spectrum.

The given wavelengths of 380-430 nm fall within the section of the electromagnetic spectrum known as visible light. This is the portion of the spectrum that is visible to the human eye, usually defined as having wavelengths between 400 nm and 750 nm. Specifically, the range of 380-430 nm corresponds to the color violet or purple in the visual spectrum.

Colors are associated with specific wavelengths, and these wavelengths define the various colors of light that we see. Violet or purple light has a shorter wavelength compared to other colors in the visible light spectrum, such as blue, green, and yellow.

Understanding the wavelengths of different colors in the visible light spectrum can provide insights into how we perceive and experience the world around us. The phenomenon of color is a fascinating aspect of our sensory perception and plays a significant role in our daily lives from art and design to science and technology.
