Why can neon lights glow in different colors?

Answer 1

The vivid colors seen in advertising lights are the result of different neon gases that each tube contains. Different gases burn at various temperatures resulting in these colors. For example magnesium produces the bright white color light.

Answer 2

Electrons in the outer most shell of neon atoms can be excited with various forms of energy. In neon lamps, these electrons are excited by the collision with another energetic electron (from the electric current source). The kinetic energy of the energetic electron can be transferred to the outer shell electrons, causing the outer shell electron to rise (excite) to a higher 'energy level'. However, this higher energy level is only maintained transiently and the excited electron falls to its original energy level, and the extra energy is released as electromagnetic radiation. If the elctromagnetic radiation is in the visual range (380 nm to 750 nm in wavelength), then it can be observed as light.

Answer 3

Neon creates inert atmosphere in lamp and it allows light . so that bulb glows brightly.

Neon is mixed with other gases to cause an inert reaction. Oxygen for Red, Argon for yellow etc. At the ends of the tubes are electrical devices called exciters which cause the color to show through the tube when they are plugged in.

Answer 4

Certain gases emit different colors in "neon" signs (which can contain elements beside neon) because of their different electron configurations. When an electric current is passed through the gas, some of the electrons in the gas molecules are excited. These electrons then return to their ground state by emitting a photon, a particle of light. The energy of the photon (which in turn determines the color of the photon) depends on the difference in energy between the excited state and the ground state. Since this energy gap is different for different elements, various gases can emit various colors of light.

Answer 5

The color of neon light will depend on the gas in the tube. The color is naturally red, but when other gases and chemicals are mixed, they produce different colors.

Answer 6

because people think that neon comes from the ancient Greeks and that many colors were created by them as they were experimenting with food and that is how neon colors came to be

Answer 7

Because the lights are filled with gases and each gas gives a different color. There are no two gases that give off exactly the same color

Answer 8

There is different mixtures of gases with each kind of color. Gases such as argon, neon, helium, mostly noble gases.
