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.

∙ 13y agoThe 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

∙ 12y agoThat 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

∙ 13y agoGamma 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 a gamma-ray burst, and how does it happen?
It happens when two gamma rays come from different stars and collide and make a big explosion . A gamma ray burst is when two gamma rays come from different stars and collide and make a big explosion. BOOM
How does the energy of a gamma ray compare to the energy of light?
they're both fast, but not as fast as me in bed ;)
How powerful are gamma ray burst?
Gamma ray bursts or GRBs are very powerful and the biggest explosion ever since the big bang. GRBs will produce more energy in a second than the sun will make in its life time.
What do we use gamma ray for?
We use Gamma Ray to make Hulk
What is the energy of a gamma ray?
A gamma ray will have energy in excess of 100 keV (kiloelectronvolts).
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 is a gamma-ray burst, and how does it happen?
It happens when two gamma rays come from different stars and collide and make a big explosion . A gamma ray burst is when two gamma rays come from different stars and collide and make a big explosion. BOOM
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 are the similarities between light and gamma rays?
Light ray and gamma ray both travel in a straight line.
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.
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 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.
Gamma-ray burst fireball model?
A gamma-ray burst, or GRB, is one of the most energetic events in the universe. The Fireball model describes why GRBs tend to have high energy levels. It also explains the time scales that govern them and why they generate an afterglow.
What is a gamma pulse?
I presume you mean a "gamma ray burst." This is a burst of gamma ray energy, lasting from less than a second to a few minutes, that comes from outside our galaxy. Despite being from that far away, they are measurable on our planet, meaning the energy release in one second of a gamma ray burst is greater than the energy that our Sun will release in its entire ten billion year life cycle. GRB's are now thought to be from the collapse of a massive star, but the question has not been completely settled. If a gamma ray burst from within our galaxy were to hit our Earth, all life on our planet, even bacteria, would end within a few days.
