It travels at the "speed of light". In vacuum, that's 299,792,458 meters per second.

In any kind of material substance, it's less. How much less depends on the

individual substance ... they're all different.

Who discovered that electromagnetic waves can travel through empty space at the speed of light?

James Clerk Maxwell is credited with discovering that electromagnetic waves can travel through empty space at the speed of light. His equations, known as Maxwell's equations, provided a unified framework for understanding electricity and magnetism.


Which describes how electromagnetic waves travel?

Electromagnetic waves travel through space at the speed of light in a wave-like pattern, with oscillating electric and magnetic fields perpendicular to each other. These waves do not require a medium to propagate and can travel through a vacuum.


How fast do electromagnetic waves travel through a vacuum?

Electromagnetic waves, such as light, travel through a vacuum at the speed of light, which is approximately 299,792 kilometers per second (186,282 miles per second). This speed is a fundamental constant of nature and represents the fastest speed at which any form of information or energy can travel through space.
