An oscillating electric field generates an oscillating magnetic field. The reverse is also true. The oscillating fields together forms what is termed an electromagnetic wave.
Radiation from the electromagnetic spectrum may be expressed in terms of energy, wavelength, or frequency. What we call light is the visible portion to the human eye which has adapted to 'see' this part of the spectrum as these are the most common wavelengths reaching Earth through the atmosphere. Technically, it could all be termed 'light'.
The visible portion is between 400-750 nanometers. Lower (larger) than 750 (red) is
infrared 750nm - 1 millimeter
microwaves 1mm - 30 centimeters
radiowaves 30cm - the width of the Earth
Higher (smaller) than violet (400) is
ultraviolet 400nm - 10nm
Xrays 10nm - 1 picometer
Gamma rays 1pm - as small as a subatomic particle
