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.
How fast is the speed of sound in a vacuum?
Sound waves cannot travel in a vacuum.
Do electromagnetic waves move in a vacuum?
yes, at 'c' the speed of light in a vacuum.
What is it that all electromagnetic waves do the same?
All electromagnetic waves travel at the same speed in a vacuum -- the speed of light.

What is the speed of ultrasonic waves in vacuum is equal to what is the speed of audible sound in air?
No, ultrasonic wave do not travel at all in a vacuum.
How fast is the speed of sound in a vacuum?
Sound waves cannot travel in a vacuum.
Do electromagnetic waves move in a vacuum?
yes, at 'c' the speed of light in a vacuum.
What is it that all electromagnetic waves do the same?

How does the sped of radio wave compare with speed of tv waves when both measured in vacuum?
Both radio waves and tv waves are electromagnetic waves. So both have the same speed in vacuum. Of course radio waves are of lower frequency compared to that of tv waves.

Is the speed in vacuum of all electromagnetic waves the same?
Yes, it is.
