Red light, in the region of 650 to 700 nm, travels further than blue.
No limit ... even across the universe ... until it hits something that absorbs it.
Light waves pertain to the frequency of light. All light is known as electromagnetic radiation and travels in the form of a wave (although it does have particle characteristic) meaning that these waves have different frequencies. A frequency tells us how often the waves goes up and down and how powerful they are. Light can also be measured by it's wave length, the distance it take for the light to go up and back down again (vice versa). A certain wavelength of light will be a different color, for example if light (Electromagnetic Radiation) has a wavelength of 650 nm (nanometers) then it will appear as the color red. Humans can only perceive light that has a wavelength in between 350 nm and 750 nm, a very small portion of all electromagnetic radiation. Here is a list of colors pertaining to their wavelength: Violet: 400 nm Indigo: 445 nm Blue: 475 nm Green: 510 nm Yellow: 570 nm Orange: 590 nm Red: 650 nm White: White is a mixture of all colors of visible light. Black: Black is an absence of light, meaning that there is no light.

If you are talking specifically about visible light, the wavelength is between approximately 380 nm and 760 nm, depending on the color.
Infrared
485 nm

The range of wavelengths that are visible is approximately 400 nm to 600 nm. A nm is a nanometer, one billionth of a meter. Blue light is in the 400 nm range, yellow light in the 500 nm range and red light in the 600 nm range.

As stated earlier: Violet light: 380-450 nm Red light: 620-750 nm nm=nanometer=10-9 meter
The wave length of visible light ranges from 400 nm to 700 nm
between 400 nm and 700 nm
Visible light ranges from red at about 750 nm to violet at around 400 nm.
between 400 nm and 700 nm
