What is the wavelength range of visible light in the electromagnetic spectrum?

The wavelength range of visible light in the electromagnetic spectrum is correctly identified as 400-700 nm. This range corresponds to the portion of the spectrum that can be detected by the human eye, facilitating our perception of color.

In this range, shorter wavelengths (around 400 nm) correspond to violet light, while longer wavelengths (up to 700 nm) correspond to red light. This transition through the range includes the full spectrum of colors typically seen in a rainbow: red, orange, yellow, green, blue, and violet. Understanding this range is crucial in fields such as photography, optics, and various applications in analytical chemistry where light absorption and emission are studied.

Other ranges listed, such as 100-400 nm or 700-1000 nm, fall outside the visible spectrum. The former includes ultraviolet light, which is not visible to the human eye, while the latter pertains to infrared light, which is also invisible. The range of 500-800 nm does not accurately encompass the full visible spectrum and includes both visible and non-visible wavelengths.
