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.

DevinThe 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.

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.
Can black holes explode?
Yes, black holes can explode in a process called a gamma-ray burst, which releases a tremendous amount of energy.
