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.

The speed of light (electromagnetic radiation) in a vacuum is always the same, no matter what type of EM radiation it is.

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.

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 a gamma pulse?

A gamma pulse is a short burst of gamma radiation, which is a high-energy form of electromagnetic radiation. It can be produced naturally from astronomical events such as gamma-ray bursts or artificially in laboratory settings for scientific research or medical purposes. Gamma pulses have the potential to damage living tissue and disrupt electronic equipment.
