Going from short wavelength light to long wavelength light, the order goes Red - Orange - Yellow - Green - Blue - Indigo - Violet (ROYGBIV)
The longest radio wave used for communication is around 3 millimeters long. The shortest visible wavelength of light is around 0.0004 millimeters long.
The shortest wavelength of visible light for your eye is the wavelength of the lastcolor you can see on the blue end of the rainbow. It may be slightly different forsomeone else's eye.
The color of visible light with the longest wavelength is red; the color with the shortest is violet. So "ROY G. BIV" lists the colors from long to short wavelength. Just to confuse you, we'll also mention that it lists them from lowest to highest frequency.
No. The speed of light is the same for long wave and short wave light. c=fw where w is the wavelength and f is the frequency. The speed c is a constant. The frequency is different for different wavelengths. High frequency for short waves and low frequency for long waves.
Both are examples of electromagnetic radiation. Infrared has a longer wavelength (lower frequency) than visible light. Of course visible light is visible to humans and infrared is not (although long wave Infrared is sensible to humans as heat).

Neither is nesesarily longer a wave can go on forever. Visible light is more reflective than infared light so it will last longer. If you are talking about wavelength, infared lights wavelength is longer.
for wavelength, the longer of the two is visible light, but the longest type of rays are radio waves (some of them have a wavelength as long as a football field)

I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
no, the wavelength of infrared light is too long for it too be seen. visible light makes up only a small portion of the electromagnetic spectrum

No. Some are longer trhan others, but they are all very short. Light visible to the human eye has wavelengths ranging from a little more than 100 micrometers (infrared) to less than 1 nanometers (ultraviolet). In reference to visible light, infrared is referred to as long wavelength and ultraviolet as short wavelength light. I can't remember the units, but the human visible area is from about 400 (deep blue) to 700 (red), so a rather more restricted range than implied above. All those wavelengths are indeed very short.
The color of visible light with the longest wavelength is red; the color with the shortest is violet. So "ROY G. BIV" lists the colors from long to short wavelength. Just to confuse you, we'll also mention that it lists them from lowest to highest frequency.
All electromagnetic waves have the same speed, as long as they're traveling through the same stuff, regardless of their wavelength.
