No. Neon lihgts may also contain ohter gases like H2, He, CO2 and Hg.
In general to produce orange light we use Neon.
to produce red light Hydrogen(H2) is used.
to produce yellow light Helium (He) is used.
to produce white light carbon dioxide (CO2) is used.
to produce blue light mercury(Hg) is used.

#1. To reduce nitrogen oxide emissions from a diesel engine, one commonly used strategy is exhaust gas recirculation (EGR). In a stack-type EGR cooler, exhaust gases flow through tubes with a rectangular cross-section (4 mm x 6 mm). In each tube, the mass flow rate of exhaust gases is 0.0001 kg/s; the gases enter at 140°C while the inner surface of each tube is maintained at 80°C due to water being circulated as a coolant. The length of the tube...

5. A light emitting diode (LED) is a diode that lights up when a current flows across it. The symbol for an LED is shown below (sometimes wiggly arrows are used to represent the light instead.) For this question we will assume we are working with LEDs that have a turn-on voltage of VoN-1V and a reverse breakdown voltage of VBR-8V a. You hook up a single LED to a power supply that can put out vol tage from -10...
