The speed of an electromagnetic wave is?

In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.In a vacuum, all electromagnetic waves have the same speed: about 300,000 kilometers per second.


How do you know the speed of an electromagnetic wave in a vacuum?

The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.


Which kind of electromagnetic wave travels fastest in a vacum?

All electromagnetic waves travel at the same speed in vacuum.


In vacuum the speed of an electromagnetic wave what is the answer?

In a vacuum, the speed of an electromagnetic wave, such as light, is constant at approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is denoted by the symbol 'c' and is a fundamental constant of nature.


How is the speed of an electromagnetic wave determined?

The speed of an electromagnetic wave is determined by the properties of the medium it is traveling through. In a vacuum, electromagnetic waves travel at the speed of light, which is approximately 299,792 kilometers per second. This speed can change when the wave enters a different medium.

How does the speed of a photon compare with the speed of an electromagnetic wave?

Light can be considered as a wave, or as a particle. As a particle, the particles are called photons. As a wave, light is an electromagnetic wave. In either case, the speed of light (in a vacuum) is approximately 300,000 km/sec.
