Different wavelengths of light have different colors.
House lights radiate energy as electromagnetic waves in the wavelength bands of heat and visible light.
The shorter the wavelength (blue rather than red), the higher the energy.
Visible light has shorter wavelengths than microwaves. Microwaves, which might be considered the highest energy radio waves, have a longer wavelength (and a lower frequency) than visible light.
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.
The longest wavelength that's visible to your individual eyes is that of the last color you can see on the red end of the spectrum. The shortest wavelength that's visible to your individual eyes is that of the last color you can see on the blue end of the spectrum. Between those lie every color you can name, every color you have ever seen, every color that any paint manufacturer can mix, and every color that any fabric designer can dye or weave. There are an infinite number of them, it's not possible to list them, and the vast majority of them don't even have names.
Most of the spectrum charts that I have seen are listed in wavelengths, particularly nanometers (nm). Where 1 nm = 1x10^-9 m.
yes
Energy = Planck's Constant * wavelength The lights will not have the same energy is the wavelength varies.
There are no northern lights in Antarctica. However, the southern lights -- Aurora Australis -- are visible from the continent.
Neon lights.
Red light has the longest wavelength and is less likely to be scattered by particles in the air. This means that red lights can be seen more easily in fog, so it makes cars more visible in bad viewing conditiions.
they are mostly visible in the Northern Hemisphere, especially in Northern Canada, Norway and Russia
