What else can I help you with?
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 is the difference between high pressure low pressure sodium lamps?
High pressure sodium lamps produce a brighter, more efficient light compared to low pressure sodium lamps. High pressure sodium lamps also have a longer lifespan and better color rendering properties. However, low pressure sodium lamps are more energy efficient and have a monochromatic yellow-orange light output.
What is the name of the rainbow colors produced from a white light?
The name of the rainbow colours produced from a white light is called the spectrum.
What gase use in flurocent lamp?
Fluorescent lamps use a mixture of gases, including mercury vapor and argon, to produce light. When electricity passes through the gases, ultraviolet light is produced, which then interacts with the phosphor coating inside the lamp to create visible light.
What happened before the light bulb?
Before the invention of the light bulb, people used candles, oil lamps, gas lamps, and other forms of illumination to light up their surroundings. The light bulb revolutionized the way we illuminate our homes and cities by providing a more efficient and reliable source of light.
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 color is produced when red and green light are combined?
When red and green light are combined, the color produced is yellow.
What element producer color yellow?
The element that produces a yellow color is sodium. When sodium is heated, it emits a bright yellow light, which is commonly seen in street lamps and fireworks.
What are two helpful effects of UV light?
Ultraviolet light produced by Ultraviolet lamps is used to kill bacteria on food and surgical tools.
Which metal vapours give yellow street light also used in fog lamps?
I think it's sodium.
What color of light is produced when red light and green light is added together?
When red light and green light are added together, yellow light is produced. This is because red and green light combine to stimulate both the red and green cones in our eyes, creating the perception of yellow.
How is uv light produced?
UV light can be produced through various methods, such as electric arcs in specialized lamps or through the interaction of certain chemicals that emit UV radiation when excited. In nature, UV light is also produced by the sun as part of the electromagnetic spectrum.
What color is made when a red light and a green light are combined?
When a red light and a green light are combined, the color produced is yellow.
Difference between tungsten lamps and carbon lamps?
tungsten lamp has got inert gas argonsometimes iodine is added to improve intensity carbon filament produces less light than tungsten lamp but it radiates much less energy in the form of heat waves
What is the difference between high pressure low pressure sodium lamps?
High pressure sodium lamps produce a brighter, more efficient light compared to low pressure sodium lamps. High pressure sodium lamps also have a longer lifespan and better color rendering properties. However, low pressure sodium lamps are more energy efficient and have a monochromatic yellow-orange light output.
What are the different types of light?
Incandescent Lamps Light Emitting Diode Neon Lamps Fluorescent Tubes Compact Fluorescent Lamps Halogen Lamps Metal Halide Lamps High Intensity Discharge Lamps Low Pressure Sodium Lamps High Pressure Sodium Lamps
Is sodium lamp monochromatic?
No, sodium lamps are not monochromatic. They emit a broad spectrum of light, with a characteristic yellow-orange color due to the dominant emission of spectral lines in the yellow region.
