Sodium lighting is more efficient to run than white lights, and it gives an even light with less glare.
What else can I help you with?
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.
Which s the most monochromatic light?
Monochromatic light is light composed of a single wavelength. One example of monochromatic light is the laser, which emits light of a very specific color or wavelength, making it highly monochromatic.
Why rate of evaporation decreases with increase in humidity?
When humidity is high, the air is already saturated with water vapor, so there is less room for additional water molecules to evaporate from a wet surface. This reduces the concentration gradient needed for evaporation to occur, leading to a decrease in the rate of evaporation.
What is the verb for vapour?
In British English, the verb of vapour is vaporise.In American English, the verb is vaporize.Other verbs depending on the tense are vaporises (US - vaporizes), vaporising (US - vaporizing) and vaporised (US - vaporized),
Solid condensation on a surface that is below 0C is known as?
Water vapour changing to solid on a surface is sublimation of the vapour. For water the product is referred to as rime or hoarfrost.
Why sodium vapour lamp are 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 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.
Which is the metal vapours used in yellow street lights?
Sodium vapour.
What element is used in the lighting of street lamps?
Sodium-vapour lamp, electric discharge lamp using ionized sodium,
Will mercury vapour work in a sodium vapour fixture?
no
Is there a use for sodium?
Sodium is used for loads of things! Sodium Chloride is table salt, sodium metal is used to prepare elements to make alloys, and sodium vapour is used in street lights. It is also key in the paper, glass and textile industry. Hope this Helps!!
What is one way in which you can identify the elements that are used in various street lights?
By the colour of the light that they emit. Sodium vapour lamps produce yellow/orange light while Mercury vapour lamps produce white light.
What happens if you use a mercury source instead of sodium vapour lamp in diffraction grating experiment?
sodium vapour lamps produce much higher light output (about 90 lumens/watt) they cannot be used in lighting applications where colour-rendering property is very crucial. This is because most of the light emitted from a sodium vapour lamp is concentrated in the yellow part of the visible spectrum (around 580-590 nm) On the other hand, a mercury vapour lamp is quite suitable for lighting applications. This is because, the mercury vapour lamp can feed almost the entire visible region (380-780 nm) of the human visual system.
When sodium bicarbonate is heated what will it release?
water vapour
Which metal vapour is used in fog lamps?
Probably sodium.
What is the source of illumination employing vapour of the element Na?
Sodium lamp
Can sodium and mercury exist in monoatomic molecule in vapour state?
No, sodium and mercury exist as diatomic molecules in the vapour state due to the nature of their chemical bonding. Sodium forms Na2 while mercury forms Hg2 molecules.
