Sodium lights are used because they are more energy-efficient and provide better visibility in certain conditions, such as in outdoor lighting or street lighting. They also have a longer lifespan compared to white lights, which can result in cost savings for maintenance and replacement.
What else can I help you with?
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.
What will be the resulting spectrum if use a monochromatic light instead of sodium vapour lamp in diffraction grating?
If monochromatic light is used instead of a sodium vapor lamp in a diffraction grating experiment, the resulting spectrum will contain a single wavelength with evenly spaced interference fringes. This is because monochromatic light consists of only one specific wavelength, resulting in a clear and distinct pattern of interference.
What will happen if we replaced sodium lamp to white source in newton ring experiments?
if white light is used in place of monochromatic light, a few coloured rings are observed. each colour gives rise to its own system snd it gives a rainbow type illuminetion. tjese rings soon superimpose and result in uniform illumination
Is a prism used to turn white light into black light?
No, a prism is not used to turn white light into black light. A prism disperses white light into its component colors through refraction, but it does not alter the light to turn it black. Black light is actually ultraviolet light that is not visible to the human eye without the help of special fluorescent materials.
How might you distinguish a sodium vapor streetlight from a mercury vapor streetlight?
Mercury vapor streetlights, used since the 1940s, glow a greenish white. Sodium vapor streetlights, which have gradually replaced most of the MV streetlights in the US, glow orange. Another two, metal halide and LED, glow completely white.
Why sodium vapours lamps are used as street light instead of simple white tube lights?
Sodium lighting is more efficient to run than white lights, and it gives an even light with less glare.
Why are sodium vapour lamps used as street lights instead of simple white tube lights?

Sodium lighting is more efficient to run than white lights, and it gives an even light with less glare.
Why sodium vapuor lamps are used as street lights instead of simple white tube lights?
High pressure sodium lamps take a while to fully light up, however they are very energy efficient and save the council money.
Which light is used in newtons rings?
sodium light
Why is sodium light used instead of white ordinary light in newton's rings?
Newton's rings are caused by interference of light waves. When monochromatic light is used, then newton's rings are alternately dark and bright .When white light is used then a few coloured rings are visible.After that due to overlapping of rings of different colours , the rings cannot be viewed. The different colored rings are obtained because of different wavelength of colors. the order of colors depend on order of ring.
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.
You are a silvery white metal used to make salt?
You are sodium, a highly reactive metal commonly used to produce sodium chloride, or table salt. Sodium is known for its silvery-white appearance and its importance in various industrial applications and chemical processes.
What will be the resulting spectrum if use a monochromatic light instead of sodium vapour lamp in diffraction grating?

What the silvery white metal used to make salt?
The silver-white metal used to make salt is sodium. Sodium is a highly reactive metal that is commonly found in salt compounds such as sodium chloride (table salt).
