Example:
Imagine trying to tune into your favorite radio station, but the dial is slightly off, so you hear static instead of clear music. Just like a radio, light consists of many different "stations" or wavelengths, not all of which we can "tune into" or see with our eyes. The visible light we see is like the clear music when the radio is perfectly tuned, while the static represents the vast range of electromagnetic energy, like ultraviolet or infrared, that exists but isn't visible to us.

Light: Electromagnetic energy that travels in waves, not all light is in the visible spectrum. Light is a form of energy that we can see with our eyes.
