Light moves at a constant speed in a vacuum because of the properties of space and time, as described by the theory of relativity. According to this theory, the speed of light is a fundamental constant and does not change regardless of the observer's motion or the source of the light.
What else can I help you with?
Which of these is constant for ALL types of electromagnetic radiation in a vacuum?
Answer = Velocity Velocity is the speed of light and, the speed of light, is a constant among Electromagnetic Radiation in the vacuum of space.
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.
What is the speed of electromagnetic radiation in a vacuum?
it is about 300,000 kilometers per second.
Is it possible for anything to move faster than light?
According to the theory of relativity, nothing can move faster than the speed of light in a vacuum.
Does speed wavelength and frequency of electromagnetic waves change in vacuum?
No, the speed of electromagnetic waves in vacuum is constant and equal to the speed of light, which is approximately 3.00 x 10^8 meters per second. However, the wavelength and frequency of the waves can change as they move through different mediums with different refractive indexes.
Which of these is constant for ALL types of electromagnetic radiation in a vacuum?
Answer = Velocity Velocity is the speed of light and, the speed of light, is a constant among Electromagnetic Radiation in the vacuum of space.
What constant speed does the light move at?
The speed of light in a vacuum (c) is 299,792,458 m/s. It is sometimes rounded to be 300,000 kilometers per second.
Why is the speed of light limited in a vacuum?
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.
What of the following statements about the speed of light is true?
nothing can move faster than the speed of light in a vacuum APEXXX

What is the speed of electromagnetic radiation in a vacuum?
it is about 300,000 kilometers per second.
How photon differ from an inertial particle?
In a vacuum, a photon can ONLY move at the speed of light. A regular particle can ONLY move at speeds less than the speed of light.
Does time always move at a constant speed?
The speed of light is always the same as long as it's traveling through the same medium. But its speed is different in different media, and those are all less than its speed in vacuum.
What is the maximum velocity of light?
The speed of light in a vacuum is 300,000 kilometers per second (or 300 million meters per second). In a vacuum, light can ONLY move at that speed - neither faster, nor slower.
Is it possible for anything to move faster than light?
According to the theory of relativity, nothing can move faster than the speed of light in a vacuum.
Does speed wavelength and frequency of electromagnetic waves change in vacuum?
No, the speed of electromagnetic waves in vacuum is constant and equal to the speed of light, which is approximately 3.00 x 10^8 meters per second. However, the wavelength and frequency of the waves can change as they move through different mediums with different refractive indexes.
What are the vibration particles that can move through a vacuum?
Electromagnetic waves, such as light, are vibration particles that can move through a vacuum. These waves do not require a medium to propagate and travel through empty space at the speed of light.
