It means that visible light can be split into a spectrum of colours. Roygbiv is an acronym which helps us remember the colours of the spectrum in order: red, orange, yellow, green, blue, indigo and violet.

That wave is called as electromagnetic wave. It has got a spectrum of very high frequency gamma rays to very low frequency radio waves. They all have the same speed. That is the speed of light.
The cones in the retina of our eyes are sensitive to certain frequencies of light within the visible light spectrum (ROYGBIV). Light waves with longer wavelengths (within the visible range of frequencies) are perceived to be on the red, orange, yellow side of the spectrum, while higher frequencies/shorter wavelengths of light appear blue or violet.
At the highest end of the Electromagnetic Spectrum are wavelengths known as Gamma Waves. Gamma Waves are a unique form of radiation that is highly dangerous to living tissue.
They are related by they are both spectrums that give the color(s) that the element is. The Emission Spectrum shows what color(s) it gives off, and the Absortion shows what color it absorbs and doesn't show. They also fit together and make a continuous spectrum.

infrared rays are in the middle, and if it is for color it is green or yellow

Yes, visible light (the color spectrum) is a tiny range of the full range of electromagnetic waves. In the related Wikipedia link, there is a picture that shows the colors 'crammed in' to a small range of the spectrum.
At the highest end of the Electromagnetic Spectrum are wavelengths known as Gamma Waves. Gamma Waves are a unique form of radiation that is highly dangerous to living tissue.
Sunlight is actually light waves of different frequencies. Some of these waves are part of the visible light spectrum (ROYGBIV), and therefore sunlight appears white, a combination of all the frequencies in the visible light spectrum. Light waves with lower frequencies appear more red or orange. Light waves with higher frequencies appear violet or blue. When sunlight shines down through the atmosphere, the particles in the air scatter the light waves of higher frequencies, therefore spreading the waves in different directions in the sky (This is why the sky appears blue). The lower frequency waves reach our eyes mostly undisturbed. Since sunlight has light frequencies dominant in yellow, that's the color we see.
these waves are known as Infrared Waves. On the EM spectrum the are between visible light and microwaves. It means "below red".
They are related by they are both spectrums that give the color(s) that the element is. The Emission Spectrum shows what color(s) it gives off, and the Absortion shows what color it absorbs and doesn't show. They also fit together and make a continuous spectrum.
The waves with the longest wavelengths are known as radio waves.
yes. the spectrum is roughly radio waves, infrared, ROYGBIV (beginning with red and ending in violet),ultra violiet, xrays, gamma rays. seeing that blues location is closer to the gamma rays than red, it is indeed more dangeous. Still it's so small that it doesn't really matter
