LPS is a monochromatic lamp and HPS is not.
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)...........
The white lamp has a softer glow for evening hours.
This could be due to the fact that a sodium vapour lamp contains neon gas and when a current is passed through the two electrodes in the lamp the neon gas becomes ionised and shines red until vapourisation occurs and the sodium cause the typical characterised yellow.
yes of-course
Peter Cooper Hewitt (May 5, 1861 - August 25, 1921) was an American electrical engineer who demonstrated the mercury-vapor lamp, for which he deposited a patent.
NO. It produces four lines with wide difference in wavelengths. So it is not a monochromatic just as sodium vapour lamp
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.

You will observe a series of bright and dark fringes uniformly spaced, of the color of the monochromatic light used.
Mono means single Chrome means colour So monochromatic means single coloured light Example: Light coming from Sodium vapour lamp ---- Monochromatic means (light) of a single frequency or, what is the same thing, of the same wavelength.
Sodium lamps only give monochromatic yellow light and so inhibit color vision at night, and cause less light pullution. You can get more details at blmall.com.
it is highly monochromatic . all standard results are in 589nm . so Na is used if you use a filter then der no other wavelength than 589 &589.6nm
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
light from sodium vapour lamb
for diffraction grating mercury lamp is used not sodium lamp.
White light is another name for polychromatic light. That is light that contains more than one wavelength. For example, sunlight is white light. An example of monochromatic light is a sodium vapour lamp or a LASER.
A sodium lamp would not disappear when added to water. However the lamp would probably never be usable again.
