_numpty_ and phrebh,

As a graduating Physics major, I can address your confusion.

In the scientific community, "light" is a blanket term for any EM wave. The difference between visible light and gamma waves, for instance, is that our eyes are not sensitive to wavelengths outside the visible spectrum. Visible light has wavelengths on the order of about 400 nanometers to 700 nanometers. Gamma waves, on the other hand, have wavelengths around 1 picometer (0.000000000001 meters). However, they are still the same electromagnetic beast, i.e. "light". Visible light waves just have wavelengths 1,000,000 times shorter than gamma waves.

That being said, whether or not the layperson calls the visible light spectrum "light" is a moot point. Light is light, no matter the wavelength. The EM spectrum is light, and vice versa.

However, I can understand the confusion. Even in the Physics discipline, nobody ever comes out and says "Light is any EM wave." You are just supposed to pick up on it. Nevertheless, whenever physicists talk about light, the mean EM waves in general. There are no specific ranges of wavelengths in mind.
