What is the difference between sodium vapor and mercury vapor streetlight?
Sodium vapor streetlights emit a warm yellow-orange light, while mercury vapor streetlights emit a bluish-white light. Sodium vapor lights are more energy-efficient and have a longer lifespan compared to mercury vapor lights. Additionally, sodium vapor lights are better at preserving night vision and reducing light pollution.
Why do sodium lights glow yellow?
Sodium lights produce yellow light because they contain sodium vapor that emits a characteristic yellow-orange light when an electric current passes through it. This yellow light is a result of the specific energy levels of the sodium atoms, which emit light in the yellow part of the spectrum.
What is the gas used in light bulbs?
Generally, argon or krypton.Argon , neon ,Argon is sometimes used in incandescent lights.Answer:Fluorescent bulbs contain mercury vapor so do mercury vapor lights, sodium vapor lights contain sodium vapor once they are hot, "neon" lights contain neon and a number of other gases depending on the color desired.Argon or nitrogenIn incandescent light bulbs (the regular kind) contain an inert gas, probably Argon. Sometimes there is no gas at all and a vacuum protects the filament.In Florescent bulbs the tubes are filled with low pressure mercury vapor along with an inert gas such as argon, xenon, neon, or krypton.argon
Sodium metal and iodine vapor form what?
When sodium metal reacts with iodine vapor, it forms sodium iodide, which is a white solid compound. The chemical equation for the reaction is: 2Na(s) + I2(g) → 2NaI(s).
The light given off by electic discharge through sodium vapor is?
The light given off by electric discharge through sodium vapor is yellow in color. Sodium vapor lamps are commonly used for outdoor lighting due to their efficient energy consumption and high brightness.
What is the difference between sodium vapor and mercury vapor streetlight?
Sodium vapor streetlights emit a warm yellow-orange light, while mercury vapor streetlights emit a bluish-white light. Sodium vapor lights are more energy-efficient and have a longer lifespan compared to mercury vapor lights. Additionally, sodium vapor lights are better at preserving night vision and reducing light pollution.
What alkali metal is used in street lights?
Sodium (chem symbol = Na) Mercury vapor is also used in street lights. Low pressure sodium vapor street lights are amber/yellow in color, high pressure sodium lights are white and mercury vapor lights glow blueish white.
What element makes street lights yellow?
The element that is used to make street lights yellow is sodium. Sodium is commonly used in sodium vapor lamps, which emit a yellowish light when an electric current passes through the sodium vapor.
What gas is in the bulb?

What gas burns orange?
Sodium vapor produces an orange flame when burned. This is commonly seen in street lights and high-pressure sodium lamps.
What element produces a bright yellow glow in street lights?
Sodium is the element that produces a bright yellow glow in street lights. This is primarily due to the emission of light in the sodium vapor inside the lamp.
Why sodium vapour lamps are used as street light instead of simple tube light?
Sodium lighting is more efficient to run than white lights, and it gives an even light with less glare.

How is sodium used as a metal?
The most visible way is in lighting. Many industrial electrical lights are based on the light given off by ionised sodium. Sodium lights are typically bright orange or a strange orange-brown colour. Each light has a little bit of metallic sodium inside the glass tube, which vaporises when it gets hot.
How might you distinguish a sodium vapor streetlight from a mercury vapor streetlight?
You can distinguish sodium vapor streetlights from mercury vapor streetlights by observing their color. Sodium vapor streetlights emit a warm orange-yellow light, while mercury vapor streetlights produce a blue-white light. Sodium vapor streetlights are also generally more energy-efficient than mercury vapor streetlights.
