Visible EM Waves
Visible light rays are the only electromagnetic wave that can be seen by the naked eye. All electromagnetic radiation is light but we can only see a small portion of this radiation which we call visible light. The cells in our eyes act as receivers tunes to the wavelengths of this narrow spectrum. Other portions of the spectrum have wavelengths that are too small or too large and energetic for our eyes to see.
All electromagnetic radiation is light.
