The average energy density is pressure P=S/c= E2/zc = DE = hc/r4.
Electromagnetic energy travels in electromagnetic waves, which are composed of electric and magnetic fields that oscillate perpendicular to each other as they propagate through space at the speed of light.
Light energy travels in the form of electromagnetic waves, which do not require a medium to propagate. These waves consist of oscillating electric and magnetic fields that move through space at the speed of light.
When an electromagnetic wave travels through a vacuum and its electric field vector is at a specific value, the wave will move in a straight line and maintain a constant speed.
Light possesses electromagnetic energy, which is a form of energy that travels in waves and consists of electric and magnetic fields.
The speed of an electromagnetic wave is 300,000,000 meters per second, which is the speed of light in a vacuum.

Light travels through space as electromagnetic radiation. This radiation consists of oscillating electric and magnetic fields that move through space at the speed of light.
Electromagnetic energy travels in waves.
Electromagnetic waves come from accelerating electric charges, often electrons in atoms. The energy given off travels in a wave that is partly electric and partly magnetic.
An electromagnetic wave is a wave with electric component and magnetic component. In free space (vacuum), an electromagnetic wave travels with the speed of light, that is 3x10^8 m/s. In fact, light is also an electromagnetic wave.
An electromagnetic wave is a form of radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge. An electromagnetic wave travels like any other form of radiation or light, except for the fact that an electromagnetic wave moves perpendicular to an electric field and a magnetic field.
