All electromagnetic waves that travel through space share the property of traveling at the same constant speed, which is the speed of light in a vacuum, approximately 3×1083\times 10^83×108 meters per second (300 million meters per second)

. This speed is a fundamental constant of nature and applies to all types of electromagnetic waves, regardless of their wavelength or frequency. Additional key common properties include:

• They are transverse waves, meaning their oscillating electric and magnetic fields are perpendicular to the direction of wave propagation

• They do not require a medium to travel and can propagate through the vacuum of space

• The electric and magnetic fields oscillate at right angles to each other and to the direction of travel, sustaining the wave as it moves through space

In summary, the defining shared property of all electromagnetic waves traveling through space is that they move at the same speed—the speed of light in a vacuum—while exhibiting transverse wave behavior and requiring no medium for propagation.
