What is the wavelength of mercury light?
485 nm
What is the color of mercury spectrum line of wavelength 576.96 nanometet?
yellow 1
Green light emitted by excited mercury vapor corresponds to a particular energy transition in the mercury atom a more energetic transition might emit?
Blue Light
What are the energy transformations of a fluorescent light bulb?
When a fluorescent lamp is turned on, the electricity excites the mercury vapor inside the tube. UV light is produced. The UV light excites the phosphor coating. The phosphorus atoms relax by releasing a visible light. Since the light emitted by the phosphorus atoms is of a spread spectrum (the frequency is not fixed), the light appears whitish. To summarize, electricity is turned into light.
Can newton's rings exp done by mercury vapour lamp?
Mercury vapour gives out several colours of different wavelength the rings formed with different colours would get overlapped and so chaotic image will be there. Therefore, it will require that you use light filters, yellow, green and blue for the different spectral lines, then you get monochromatic light and not a chaotic image at all.
What is the wavelength of mercury light?
485 nm
What 2 planets can be seen from earth?
There are actually five planets that can be seen from Earth. They are Venus, Mars, Saturn, Jupiter, and Mercury. Sometimes they are visible to the human eye but sometimes binoculars are needed.
A strong line in the spectrum of atomic mercury has a wavelength of 254 nm When mercury emits a photon of light at this wavelength the frequency of this light is?
254 nm= 254 x 10-9 m C=λv 3.00 x 108 m/s= 254 x 10-9 m (v) v= 1.18 x 1015 Hz
Why is mercury used in streetlights?
The light emitted by excited mercury gas is predominantly in the visible spectrum and as a light source is relatively efficient.
Mercury emitted from burning coal can stay airborne for how long?
That will be 2 years. (textbook)
What is the color of the light from the mercury lamp OF A mercury lamp emits radiation with a wavelength of 436 nm?
1 nm = 1e-9m (1 times 10 to the power -9); the basic formula for wavelenght and frequency is: (speed of the wave) = (wavelength) x (frequency); therefore, since the speed of light is 300e6 m/s, the frequency is 300e6 / 400e-9 = 0.75e15 or 750e12 (750 trillion cycles per second).
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.
What is the color of mercury spectrum line of wavelength 576.96 nanometet?
yellow 1
What impact does a dead battery have on the environment?
Toxic metals emitted as the battery decomposes (e.g. lead, mercury).
Green light emitted by excited mercury vapor corresponds to a particular energy transition in the mercury atom a more energetic transition might emit?
Blue Light
What is the wavelength of mercury in its elemental form?
if i knew, it would be a great help to the AS coursework i have to hand in tomorrow :)
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.
