What type of light source is typically used in a polarimeter to measure the rotation of polarized light?
A polarimeter typically uses a monochromatic light source, such as a sodium lamp or a laser, to measure the rotation of polarized light.
What will happen if mercury lamp is used instead of sodium lamp in plane diffraction grating exp?
Using a mercury lamp instead of a sodium lamp in a plane diffraction grating experiment might result in a different wavelength of light being emitted. This would affect the interference pattern observed on the screen, leading to a shift in the position of the fringes. Additionally, the intensity of the light and the overall visibility of the interference pattern might also be altered.
What type of measurement can be used to differentiate between sodium chloride and sugar when dissolved in water?
One way to differentiate between sodium chloride and sugar when dissolved in water is by measuring the electrical conductivity of the solution. Sodium chloride dissociates into ions in water, making the solution conductive, while sugar does not dissociate and does not conduct electricity. Alternatively, you could also use a polarimeter to measure the rotation of polarized light passing through the solution. Sodium chloride does not affect the rotation of light, while sugar does, allowing for differentiation between the two compounds.
What is the predominant wavelength associated with the emission from atomic sodium?
The predominant wavelength associated with the emission from atomic sodium is around 589 nanometers, which corresponds to the bright yellow light observed in a sodium vapor lamp or in a flame test for sodium ions.
Why is sucrose use for polarimeter calibration?
Sucrose is used for polarimeter calibration because it is a standard reference material with a well-defined specific rotation value. By measuring the rotation of light passing through a sucrose solution of known concentration, the polarimeter can be calibrated to ensure accurate measurement of optical rotation in other samples.
What type of light source is typically used in a polarimeter to measure the rotation of polarized light?
A polarimeter typically uses a monochromatic light source, such as a sodium lamp or a laser, to measure the rotation of polarized light.
What is use of half shade polarimeter?
well a polarimeter is an instrument for measuring the polarization of light. But Ive never heard of a half shade polarimeter and nor has Google :D
Can you use a sodium lamp in a mercury ballast?
No you can't. You can use a metal halide lamp of the exact wattage of the original mercury lamp. You cannot vary on wattage at all.
Can you use a led lamp in a 100w sodium fixture?
Probably not. Sodium light fixtures generally have a "ballast".
Half shade polarimeter?
in this the one half of the polarimeter is made of glass and other half of the polarimeter is made of quartz
Why does sodium lamp disappear when added to water?
A sodium lamp would not disappear when added to water. However the lamp would probably never be usable again.
What element is used in the lighting of street lamps?
Sodium-vapour lamp, electric discharge lamp using ionized sodium,
What to use to power a sodium bulb?
To power a sodium vapor lamp, you typically need a ballast specifically designed for high-pressure sodium lamps. This ballast helps regulate the electrical current to the lamp, which is crucial for proper operation and longevity of the bulb. It is important to use the correct ballast to avoid damaging the lamp or creating a safety hazard.
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.
Why is it the sodium chloride can turn the bulb on?
You think probable to a sodium vapors lamp.
Which high intensity disharge bulb do you use to grow weed?
The bulb should be in the red end of the light spectrum. One HID lamp is the high pressure sodium lamp.
Is argon gas a part of a high pressure sodium lamp?
From Wikipedia, high pressure sodium lamps use xenon, whilst low pressure ones use neon with a small amount of argon. See entry for 'sodium vapor lamps'
