Yes, they travel some fast!

Because gamma rays are exactly the same thing that light is, only with shorter wavelengths.

UV rays and all forms of radiation travel at the speed of light. Speed of light = 299,792,458 meters/second (source: Wikipedia) extremely fast, faster than alex holman taking a dump!

Neutrinos can be nearly as fast as light. All electromagnetic radiation (light, X-rays, gamma rays, radio waves, microwaves) travels at the same speed. Gravitons, if they exist, travel at the speed of light.

Gamma rays travel exactly the speed of light because gamma rays are light

Speed of light, about 300 million meters/second.

Light Rays travel in straight paths as transverse waves. It needs no medium to travel along.

Specifically,lights travel 1,342,687 miles in 0.30456 seconds.You might not believe it,but it's true.

Gamma rays travel at the speed of light because both light and gamma rays are variants of the same thing: electromagnetic radiation.

X-rays are a kind of electromagnetic radiation - similar to light. They travel at the speed of light through a vacuum - about 300 million meters/second.

If light rays did not travel through space there would be no way for them to reach Earth.

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

Light rays travel in straight paths as transverse waves. It needs no medium to travel along.

Light travels at the same speed anywhere in space. Radio, heat, and X-rays also travel at that same speed. 299,792,458 meters per second 186,282 miles per second So it takes approximately 8 minutes for the light to travel from the sun to the earth. which is mighty fast.

nothing they travel in straight line

No, x-rays travel at the same observable speed as any other electromagnetic wave including light.

If it is borne by wind blown dust and small particles, then as fast as the wind, potentially. If it is direct radiation like gamma rays, then this travels at the speed of light.

It does not, it travels as a wave

Visible light and x-rays are both forms of electromagnetic radiation, and do not require a medium to travel through.

No, they travel at the same speed of light that is 299,792 kmsec-1(in vacuum).

light rays converge at the focal plane

All the electro-magnetic waves travel at the speed of light. Electromagnetic spectrum includes the following: * X-rays * Gamma rays * Ultraviolet rays * Infrared waves * Microwaves * Radio waves * Cosmic rays
