The field emitted by the reaction in the tube which is near 1000 degrees f emits
ultra high radiation. The radiation although in a small amount if exposed over a long
period of time has been thought to cause cancer, impotency and other maladies.

Answer #2:
I've just now examined the emission spectrum of sodium in an electrical discharge,
and according to the layout I saw, ALL of the emission lines of sodium fall in the
visible band, between roughly 460 and 590 nanometers, with the doublet at about
590 nm being by far the strongest.
I've never heard of any serious objections to sodium municipal lighting on public health
grounds, and I don't know where the first answer came from.
Allegations like "has been thought" or "is reported" or "is suspected" or "studies show"
don't generally mean much if their source isn't identified, and the phrase "ultra high
radiation" is meaningless on its face.
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 gives off visible light under an ultraviolet light?
Fluorescent materials, phosphorescent materials, and objects containing fluorescent dyes or pigments can emit visible light when exposed to ultraviolet light. This phenomenon occurs as the ultraviolet light excites the molecules within these materials, causing them to re-emit visible light at a longer wavelength.
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.
How is ultraviolet light produced?
Ultraviolet light is produced when atoms or molecules absorb energy from various sources such as the sun, certain specialized lamps, or electrical discharges. This absorbed energy causes the electrons within the atoms or molecules to jump to higher energy levels, and when they fall back to their normal state, they emit ultraviolet light.
Do galaxies emit light?
Yes, galaxies emit light primarily from the stars within them. This light can range from visible light to other forms of electromagnetic radiation such as radio waves, infrared, ultraviolet, and X-rays. The light emitted by galaxies allows astronomers to study their composition, age, and distance from Earth.
What is the difference between UV lamps and IR lamps?
UV lamps emit ultraviolet light, which is invisible to the human eye and is commonly used for disinfection purposes. IR lamps emit infrared light, which is also invisible but is used for applications such as heating or drying. The main difference is the wavelength of light they emit and their respective uses.
How do you make the ultraviolet light?
Ultraviolet light is typically generated using ultraviolet lamps or LEDs that emit light in the ultraviolet spectrum. These devices use electrical energy to excite atoms, resulting in the emission of ultraviolet light. UV light can also be generated by natural sources like the sun.
What light gets emitted by tanning lamps?
Tanning lamps mainly emit UVA and UVB light. UVA light penetrates deeper into the skin and is responsible for tanning, while UVB light is more associated with sunburn. Some tanning lamps also emit UVC light, which is mostly absorbed by the ozone layer and doesn't reach the Earth's surface in significant amounts.
How do you make ultraviolet light?
First all you have to do is paint a regular bulb black.
Sources of light in a spectrophotometer?
In a spectrophotometer, the most common source of light is usually a tungsten-halogen lamp or a deuterium discharge lamp. Tungsten-halogen lamps emit a continuous spectrum of light, while deuterium lamps emit light in the ultraviolet region. These light sources provide the necessary illumination for the sample to absorb or transmit light, which is then measured by the spectrophotometer.
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 type of electromagnetic radiation is used in street lights?
Street lamps are designed to emit visible light. Some of them do this by first emitting ultraviolet radiation that is converted to visible light by a coating on the inside of the light bulb.
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.
What gives off visible light under an ultraviolet light?
Fluorescent materials, phosphorescent materials, and objects containing fluorescent dyes or pigments can emit visible light when exposed to ultraviolet light. This phenomenon occurs as the ultraviolet light excites the molecules within these materials, causing them to re-emit visible light at a longer wavelength.
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.
Is sodium lamp a monochromatic source?
sodium light is not monochromatic but we consider it because sodium light is made up of two wavelengths i.e dichromatic having little difference in their values (5890 and 5896 A) n we take their mean value (5893 A)...........
Why sodium lamp is not used in transmission grating?
Sodium lamps emit light at specific wavelengths that may not be suitable for the transmission grating efficiency curve, leading to poor performance. Additionally, the low-intensity output of sodium lamps may not provide enough light for accurate spectroscopic measurements that typically require a light source with higher intensity levels. Lastly, sodium lamps can be prone to fluctuations and instability, which can complicate the spectroscopic analysis when using a transmission grating.
