How does ultraviolet radiation compare to blue waves?

Ultraviolet (UV) radiation has shorter wavelengths than blue light. The electromagnetic spectrum is organized by wavelength, with longer wavelengths appearing at the red end and shorter wavelengths at the violet end. Blue light typically ranges from about 450 to 495 nanometers, while ultraviolet radiation ranges from about 10 to 400 nanometers.

This distinction is critical in understanding how different types of light interact with matter, including the human eye. UV radiation is not visible to the human eye and can cause damage to biological tissues, whereas blue light is within the visible spectrum and is processed by the eye. Understanding the differences in wavelength helps to inform safety measures regarding exposure to different types of light, particularly in contexts such as vision care and the use of protective eyewear.
