This national public education campaign is designed to increase awareness among parents of children ages 8 to 12 about the causes and prevention of noise-induced hearing loss.
Our eyes are what allow us to see. Our eyes are designed to detect a small portion of the electromagnetic spectrum. This part of the spectrum is called the visible light region. The visible light region ranges in wavelengths from about 380 or 400 nm to 700 or 780 nm depending on which source is used. In fact it also depends on the sensitivity of a specific persons eyes.
The only electromagnetic radiation that Humans can truly see unaided is visible light (the colors in the rainbow). Humans can sense Infrared light with their skin, and â¦ they can sort of sense X-rays, Gamma rays, and UV light if you count getting cancer, radiation sickness, or a sunburn sensing.     Humans can see radiation over the entire spectrum with instrumental aids such as IR cameras and Spectrum Analysers.
