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)...........

Is sodium lamp a monochromatic lamp?
LPS is a monochromatic lamp and HPS is not.
Why sodium lamp is prefer on white lamp during night?
The white lamp has a softer glow for evening hours.
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.
Why a sodium vapour lamp gives pink colour followed by yellow?
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.
Can you use a sodium lamp for finding dispersive power of prism?
yes of-course
Is sodium lamp a monochromatic lamp?
LPS is a monochromatic lamp and HPS is not.
Is hydrogen light a monochromatic source?
NO. It produces four lines with wide difference in wavelengths. So it is not a monochromatic just as sodium vapour lamp
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.
Is the light from an incandescent lamp monochromatic?
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.
What will be the resulting spectrum if use a monochromatic light instead of sodium vapour lamp in diffraction grating?
You will observe a series of bright and dark fringes uniformly spaced, of the color of the monochromatic light used.
What is monochromatic in physics terms?
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.
What is the source of illumination employing vapour of the element Na?
Sodium lamp
What is the source of illumination employing vapor of the element Na?
Sodium lamp
Why should we use sodium lamp for light sensitive materials?
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.
Why you use sodium lamp in polarimeter?
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
Which s the most monochromatic light?
light from sodium vapour lamb
Why resistance use in sodium vapor lamp in series with electrodes?
Because once the sodium vapor ionizes the lamp effectively becomes a short circuit, the series resistor limits the current to a reasonable value that will not overload the power source.
