Why does a vacuum and a electromagnetic wave travels the same speed?
A vacuum doesn't travel. All electromagnetic wavestravel at the same speed in vacuum.
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.

Do electromagnetic waves travel at the same speed in a vacuum?
Yes. The light is an example of a electromagnetic wave and its speed is constant.
What is the speed of an electromagnetic wave that has a frequency of 7.8 x 10 6?
The speed of every electromagnetic wave is 299,792,458 meters per second in vacuum, regardless of its frequency.

What is the speed of any electromagnetic wave?
In a vacuum, any electromagnetic wave will move at the "speed of light", which is about 300,000 km/second.
In a vacuum all electromagnetic wave have the same?

Do electromagnetic waves travel at the same speed in a vacuum?
Yes. The light is an example of a electromagnetic wave and its speed is constant.
Is the speed of a radio wave in a vacuum greater than the speed of a gamma ray?
No. The speed of all electromagnetic radiation is the same in vacuum, from the longest radio wave to the shortest gamma wave.

The speed of every electromagnetic wave is 299,792,458 meters per second in vacuum, regardless of its frequency.
Which light wave has the fastest speed?
All electromagnetic waves travel at the same speed in vacuum.
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.
