The question is not quite clear. The speed of electromagnetic waves has been

measured, in a great number of experiments of increasing precision and accuracy

over the past 150 years, and is now known correctly to within 5 parts per billion.

Why is velocity of electromagnetic waves not measured?

Electromagnetic Waves all have constant velocity which are equal to the speed of light. It is only the frequency of the wave that differentiates ie between radio, gamma, X-ray. The velocity is always fixed at 3 x 10^8 ms^-1 which is equivalent to the speed of light.


What is the frequency of electromagnetic waves measured in?

The frequency of electromagnetic waves is measured in hertz (Hz), where 1 Hz equals one cycle per second.


Is the velocity of light more than velocity of radio waves?

No as they are both electromagnetic waves so have the same velocity but have differing wavelengths and frequencies.


How are the distances to stars measured?

by the property of reflection or electromagnetic waves


What unit is waves velocity measured in?

Meters per second


In a vacuum all electromagnetic waves have?

In a vacuum, all electromagnetic waves have equal velocity.


Which property of electromagnetic waves is measured in Hertz?

The frequency of electromagnetic waves is measured in Hertz (Hz). Frequency represents the number of wave cycles that pass a given point per unit of time.


How are electromagnetic waves used to operate an xray machine?

Electrons impact at high velocity on a tungsten anode. The tungsten emits the X-Rays, which are the electromagnetic waves.


It is said that time flies but can its velocity be infinite?

Electromagnetic waves are limited to velocity "c". But time has no speed limit.


Electromagnetic waves travel at the same what?

Electromagnetic waves in a vacuum all travel at the same velocity, the speed of light (about 3 x 10^8 m/s).


What is the relationship between the frequency and the velocity of electromagnetic energy?

The frequency of electromagnetic energy is directly proportional to its velocity. As the frequency increases, the velocity of the electromagnetic energy also increases. This relationship is a fundamental property of electromagnetic waves, such as light.


In any one material all electromagnectic waves have the same?

In any one material all electromagnetic waves have the same velocity. Electromagnetic waves traveling through a medium travel at the same speed.
