What type of light is mercury?
The lamps can be constructed to emit primarily in the UV-A (around 400 nm) or UV-C (around 250 nm). High-pressure mercury-vapor lamps are commonly used for general lighting purposes….Emission line spectrum.
Wavelength (nm) | Name (see photoresist) | Color |
---|---|---|
435.8 | G-line | blue |
546.1 | green | |
578.2 | yellow-orange | |
650 | red |
Which light source is monochromatic?
LASER
Source of monochromatic light LASER(Light Amplification By Stimulated Emission Of Radiation) is a well-known monochromatic light source. A laser light results from one atomic transition with a specific single wavelength, which results in a monochromatic light beam.
What is polychromatic and monochromatic light give examples?
light made up of only one single component is called a monochromatic light eg laser beams are monochromatic. polychromatic light is light made of different colors or spectrum of rays with different wavelengths and frequencies. eg. normal sunlight is a polychromatic light.
Is fluorescent lamp monochromatic?
As you can see from the plots of spectra of different fluorescent lamps as given here, you can definitely say: yes, it’s certainly polychromatic.
Is mercury monochromatic light?
There is no monochromatic light.
What is a mercury light bulb?
Mercury, an essential part of CFLs, allows a bulb to be an efficient light source. On average, CFLs contain about four milligrams of mercury sealed within the glass tubing. By comparison, older thermometers contain about 500 milligrams of mercury – an amount equal to the mercury in over 100 CFLs.
Is light monochromatic?
Monochromatic light is light (optical radiation) where the optical spectrum contains only a single optical frequency. Light sources can also be called monochromatic, if they emit monochromatic light. The antonym of monochromatic is polychromatic.
Is mercury a monochromatic?
Is a mercury light source monochromatic or polychromatic? – Quora. A mercury vapor light source gives off light in the many spectrum and even in the invisible spectrum as UV radiation. So as a result, it is a polychromatic light source.
Is a mercury vapor light source polychromatic?
A mercury vapor light source gives off light in the many spectrum and even in the invisible spectrum as UV radiation. So as a result, it is a polychromatic light source. The resultant light is visible as close to as white light which is the combination of the three primary colors. Examples of mercury light sources are,
What is a monochromatic light source?
Monochromatic light source: Elements in gaseous state emits certain light at certain wavelengths. Such as sodium emits at 4890A. These lights are monochromatic and has been in use as monochromatic light source for more than a century. Common examples are Sodium lamp, mercury lamp, spark lamp etc.
What are some examples of mercury light sources?
Examples of mercury light sources are, CFL – the common household bulbs. Fluorescent tube lights. Mercury Vapor arc lamps – these are the brightest among the mecury light sources.
Is Mercury a heavy or light element?
Mercury is a heavy element (Atomic Number = 80) that exists as a liquid at room temperature, and is easily volatilized to a vapor. This makes it an ideal candidate for using in a mercury lamp.
