The speed of electromagnetic radiation is a constant. Its value is exactly
299,792,458 metres per second (about 186,282 miles per second) in vacuum,
somewhat slower in material media.
To give you some kind of a feeling for that speed, it would be the equivalent
of 7 1/2 times around the Earth in one second.
The speed is the same for all electromagnetic radiation. Gamma rays are one form
of it. Others include radio, microwave, visible light, ultraviolet, X-rays, etc.
Gamma ray bursts can travel at nearly the speed of light, which is about 186,282 miles per second (299,792 kilometers per second). This incredible speed allows gamma rays to traverse vast distances across the universe in a very short amount of time.
The speed of light (3x10^8 m/s) as it is an electromagnetic wave and they all travel at this speed in a vacuum. This number can be used for gases as well as the molecules are so spread out at normal temperatires
Same as speed of light "C". Gamma Rays are also form of Electro Magnetic Radiations
All EMR incl Light travel at same speed in same medium.
Which is normally approximated to 3 x 10^8 m/s
That depends on the type of radiation and sometimes where it comes from. Electromagnetic radiation (gamma rays, xrays, light rays etc) all travel at the speed of light; 3 x 10^8 m/s , regardless of their source. Beta rays & alpha rays are particles and can have any speed , less then the speed of light. Their speed will depend on their source.
radiation (heat) from the sun also travels at the speed of light
Gamma rays are electromagnetic radiation, physically identical to radio, heat, light, microwave, etc., but with shorter wavelength (higher frequency).
They travel at the 'speed of light': 300 million meters (186 thousand miles) per second.

A gamma particle travels at the speed of light in vacuum, which is 3 x 108 m s-1.
3.0 x 10^8 m/s
or
299 792 458 m / s

What is the amplitude in a gamma ray burst?
The amplitude of a gamma-ray burst refers to the peak brightness of the burst. It is the measure of how intense the burst is at its peak emission. Gamma-ray bursts are extremely energetic and can release more energy in seconds than the sun will emit in its entire lifetime.
What is a gamma-ray burst, and how does it happen?
A gamma-ray burst is a brief and extremely energetic explosion of gamma rays that comes from deep space. It is thought to be generated when massive stars exhaust their nuclear fuel and collapse into a black hole or neutron star, releasing a huge amount of energy in the process.
How much energy is a gamma ray burst compared to the sun energy output?
A gamma-ray burst can release as much energy in a few seconds as the Sun will emit over its entire lifespan of about 10 billion years. They are one of the most energetic events in the universe.
How hot is a gamma ray burst?
Gamma ray bursts can reach temperatures of several billion degrees Kelvin, making them one of the hottest events in the universe. The energy released during a gamma ray burst can be more than a supernova explosion and can outshine the entire galaxy for a brief moment.
How far a gamma ray can travel?
Gamma rays can travel long distances through space, potentially millions of light years, due to their high energy and lack of mass. On Earth, the distance gamma rays can travel depends on the material they encounter, with higher-energy gamma rays penetrating further than lower-energy ones. In dense materials like lead, gamma rays may only penetrate a few centimeters, while in air they can travel several meters.
Why black holes form Gamma ray burst?
The black holes from Gamma ray usually burst because of their energetic form.
What would happen to earth if it got hit by a gamma-ray burst?
Earth gets hit every day by gamma-ray bursts - from far, far away. Depending on how near the gamma-ray burst is, it may cause some serious damage.
What are the release dates for Mega Disasters - 2006 Gamma Ray Burst 2-3?
Mega Disasters - 2006 Gamma Ray Burst 2-3 was released on: USA: 18 September 2007
What if earth were hit by a gamma ray burst?
The earth would be completely destroyed.
What is the amplitude in a gamma ray burst?
The amplitude of a gamma-ray burst refers to the peak brightness of the burst. It is the measure of how intense the burst is at its peak emission. Gamma-ray bursts are extremely energetic and can release more energy in seconds than the sun will emit in its entire lifetime.

How much hotter is a gamma ray burst than the sun?

What can scientists do to prepare for a gamma ray burst?
At our current level of technology absolutely nothing.
What are the similarities between light and gamma rays?
Light ray and gamma ray both travel in a straight line.
Is a gamma-ray burst more powerful than a pulsar?
A gamma ray burster emits an amount of gamma ray energy in one pulse roughly equal all EM radiation energy of a galaxy in a year. So yes.
What would happen if a gamma ray burst hit the earth?
If a gamma ray burst hit Earth, it could potentially strip away the ozone layer, leading to an increase in harmful ultraviolet radiation from the sun. This could have catastrophic effects on the environment and life on Earth. However, the likelihood of a gamma ray burst hitting Earth directly is very low.
What is gamma ray bursts?
A gamma ray burst results from an extremely energetic implosion/explosion, as in supernovae or hypernovae events, or the less likely possibility of the combination of 2 neutron stars.
