What will happen if mercury lamp is used instead of sodium lamp in plane diffraction grating exp?
for diffraction grating mercury lamp is used not sodium lamp.
When alchohol and mercury boil they both change from a liquid to what?
They change from a liquid to a vapor (gas).
What is the type of gas in an arc lamp?
A combination of neon, argon, xenon, krypton, sodium, metal halide, and mercury. The common fluorescent lamp is a low pressure mercury arc lamp.
Can mercury evaporate?
Yes, at room temperature its vapor pressure is about 0.1 Pa (0.0001 kPa, 0.000001 atm.). Be carefull, vapor of Mercury is very toxic.
Is mercury being heated to produce mercury vapor a physical change?
YES, because evaperation is the same as changing it in to a gas which is a physical change.
Does a metal halide and mercury vapor use the same ballast?
No. A mercury vapor lamp will work on a metal halide ballast, but not the other way around.
Which light is brighter Metal Halide or mercury Vapor?
Between Metal Halide and Mercury Vapor the higher output is emitted from the Metal Halide lamp.
When a common fluorescent lamp is on the mercury vapor inside is actually in a which state?
Gas state
Fluorescent lamp low pressure mercury vapour?
A fluorescent lamp refers to a low pressure mercury-vapor gas-discharge lamp that uses fluorescence in order to produce visible light. It is also called a fluorescent tube.
Why Mercury vapours are used in Mercury vapor lamp?
Ionized mercury vapor radiates in the near ultra-violet (a high energy source of radiation) which energizes the fluorescent coating inside the bulbs.
Can anyone brief me on working of fluoroscent lamp?
Mercury inside the lamp creates a vapor in which current passes and heats the vapor which in turn glows however, the light that is given off is ultraviolet and can't be seen by the human eye. But, the interior of the lamp is coated with a fluorescent material which converts the UV into visible light.
What is CFL mhl and hpmv lamps?
The abbreviations are CFL - Compact Fluorescent Lamp, MHL - Metal Halide Lamp, HPMV - High Pressure Mercury Vapor, and one more is HPS - High Pressure Sodium lamp
Who invented sodium vapor lamp?
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.
Why you use mercury lamp instead of ordinary light or sodium lamp in constant deviation?
we use mercury lamp instead of ordinary lamp because ordinary lamp has many wavelengths when mercury lamp has single wavelength so in constant deviation we use only mercury lamp.
Is there a white blue lamp in fluorescent lamps?
No, the light is produced by an electrically charged low presure mixture of mercury vapor and rare earth phosphors.
Why compact fluorescent bulb doesn't work well in cold weather?
Fluorescent lamps contain a small amount of mercury that must be vaporized to allow current to flow through the lamp and cause it to light up. The colder the lamp, the more mercury is in liquid form and not vapor form, causing a lower light output in the lamp.
Which puts out the greater percentage of its energy as light an incandescent lamp or a mercury vapor lamp?
I would compare lamps of the same wattage to see which one puts out more lumens, which is the measurement of actual light output.
