Electromagnetic waves can travel through a vacuum (empty space). Examples of electromagnetic waves include radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays.
The type of wave that can travel through a vacuum or empty space is an electromagnetic wave. Electromagnetic waves are produced by the acceleration of electrically charged particles and consist of alternating electric and magnetic fields that are perpendicular to each other and to the direction of the wave propagation. These waves can travel through a vacuum because they do not require a medium to propagate, unlike mechanical waves such as sound waves.
