Yes, all travel at the speed of light.

The Electromagnetic Spectrum.
Gamma radiation is the fastest, as it is light. speed of gamma radiation = c (light speed) speed of beta radiation < c ( below light speed ) speed of alpha radiation < c/10 ( far below light speed )
Yes it does. It contains all the forms of radiation, but 99% of its energy is carried by radiation with wavelengths between 278 and 4600 nm, with the maximum at 4720 nm.
Visible light is a small region of the electromagnetic spectrum that is characterized by a specific range of wavelengths and frequencies
When electromagnetic radiation is arranged to wavelength and frequency it forms the electromagnetic spectrum.
beyatch,
All forms of radiation, even hard nuclear radiation, is a part of the electromagnetic spectrum.
The Electromagnetic Spectrum.
Technically, yes. A laser is a concentrated beam of monochromatic (usually) light. Given that light itself is considered to be part of the electromagnetic spectrum and that that spectrum is referred to as electromagnetic radiation (as it doesn't need a medium to travel through) then one could deduce that a laser beam is radiation. In addition, gamma radiation also forms part of the electromagnetic spectrum.
visble spectrum
Light (electromagnetic radiation) forms a continuous spectrum there are no two main types.
Gamma radiation is the fastest, as it is light. speed of gamma radiation = c (light speed) speed of beta radiation < c ( below light speed ) speed of alpha radiation < c/10 ( far below light speed )
Yes it does. It contains all the forms of radiation, but 99% of its energy is carried by radiation with wavelengths between 278 and 4600 nm, with the maximum at 4720 nm.
Yes. Precisely.
Yes. They're both forms of the same thing, called "electromagnetic radiation". Other forms you may have heard of include heat, microwave, ultraviolet, and X-rays. All the same thing, and travel at the same speed.
It is electromagnetic radiation that needs no medium to travel in. Gamma rays, light and radio waves, all forms of electromagnetic radiation, can travel through the vacuum of space very well. In fact, they prefer it.
