electromagnetic wave
Photon's traveling form
An electromagnetic wave is a self-propagating disturbance of electric and magnetic fields traveling through space.
Light, radio waves, X-rays, and microwaves are all electromagnetic waves, differing only in wavelength and frequency.
Unlike sound waves, they require no medium—they travel through vacuum at the speed of light.
