Light therapy utilizes a range of wavelengths. Which of the following is NOT one of them?

Visible
Ultraviolet
Infrared
Far infrared

The correct answer is: Ultraviolet

Light therapy indeed uses several ranges of wavelengths for various therapeutic purposes, primarily within the visible, infrared, and far infrared spectrum. Visible light consists of wavelengths within the spectrum that are perceptible to the human eye, while infrared light has longer wavelengths that are not visible but can penetrate deeper into the skin, promoting healing and reducing pain. Far infrared, which is the longest wavelength of infrared light, is used in certain therapeutic practices for its ability to generate warmth and promote relaxation in the body's tissues. Ultraviolet (UV) light, while it has applications in certain dermatological treatments—such as in phototherapy for psoriasis or acne—is generally not classified under light therapy in the same context as the other wavelengths mentioned. UV exposure carries risks such as skin damage and increased cancer risk, which is why it is not typically included in standard light therapy protocols aimed at skin treatment or rejuvenation. Thus, the correct identification of ultraviolet light as not being one of the wavelengths utilized in general light therapy is grounded in the nature and safety considerations of light therapy practices.
