The electromagnetic (EM) spectrum is the entire range of frequencies that electromagnetic radiation can have. The EM spectrum is divided into sections based on the common characteristics that certain frequency ranges have. These sections are, in order from low to high frequency, radio waves, microwaves, infrared waves, visible light (which from low to high frequency is further divided into red, orange, yellow, green, blue, indigo, and violet), ultraviolet waves, X-rays, and gamma rays. You can think of the EM spectrum as an invisible rainbow with visible light being a small part of it. And, like a rainbow, the edges of the divided sections are blurry; i.e. there is no exact frequency where one can say, for example, that this wave is no longer an X-ray, but is instead a gamma ray.
it is waves of light in order of their wavelengths and frequencies

Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.
between 400 nm and 700 nm
Gamma rays down to Radio waves, basically the entire EM spectrum.
Cosmic rays are not part of the EM spectrum -- they are high energy charged particles.
these waves are known as Infrared Waves. On the EM spectrum the are between visible light and microwaves. It means "below red".
Most of the EM spectrum is visible light.
Wavelength and frequency :)
The primary EM spectrum colors are red, green, and blue. These colors can be combined in different ways to create all the other colors we see in the visible spectrum.
Waves are a broad category on the electromagnetic (EM) spectrum that includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. They differ from each other in terms of their wavelength and frequency.
Electromagnetic (EM) waves are arranged in the spectrum based on their wavelength or frequency. From longest to shortest wavelength/frequency, the EM spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. This arrangement is important because each region of the spectrum has unique properties and interactions with matter.
Radio waves are the longest lengthwise.
Gamma rays
It is certainly a very important part, but it is not a major part; 'visible light' makes up only a tiny part of the EM spectrum.
Visible and infra red parts of the EM spectrum
Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.
Only their wavelengths are different.
They have different wavelength.
