The type of light that is placed just before ultraviolet light in the electromagnetic spectrum is visible light. The electromagnetic spectrum is organized by wavelength, with different types of radiation having different energy levels and frequencies.

Visible light occupies the middle portion of the spectrum, spanning wavelengths approximately from 400 nanometers (violet) to 700 nanometers (red). Ultraviolet light follows visible light, starting at wavelengths shorter than those of visible light, typically around 10 nanometers to 400 nanometers. The orderly arrangement of the electromagnetic spectrum places visible light right before ultraviolet light, indicating that as wavelengths decrease, the energy levels increase, moving from visible light to ultraviolet light.

This close relationship in the spectrum helps to explain various phenomena, such as why certain materials might glow under UV light or the effects of UV exposure on skin, which is often subjected to its energies just above the visible range.
