What compound between phenolphthalein and fluorescein are expected to have the greater quantum yield of fluorescence?
phenolphthalein will have a greater quantum yield because dissolved oxygen can reduce the fluorescence intensity
What is the unit of luminious intensity?
candela--------------------------------------------The official international definition of candela (1979) is:"The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 10e12 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian".
What is the unit of sound intensity?
Decibel
Unit of sound intensity?
The unit of sound intensity I is watts per meter squared (W/m²). Sound intensity is a sound energy quantity. Sound pressure deviations are moving our eardrums. The unit of sound pressure p is pascals (Pa) or newton per meter squared (N/m²). Sound pressure is a sound field quantity. Another answer: The most common unit of sound intensity is the decibel (dB). Reply: No! We got the sound intensity measured in W/m² and the sound intensity level we measure in decibels (dB). The question was "sound intensity".
What is the Cgs unit of luminous intensity?
stilb(sb)
How do you calculate the relative intensity of fluorescence?
The relative intensity of fluorescence can be calculated by dividing the fluorescence intensity of the sample of interest by the fluorescence intensity of a reference standard under the same conditions. This ratio provides a measure of the relative fluorescence properties of the sample compared to the reference standard.
What is Relative Fluorescence Intensity?
Relative fluorescence intensity is a measure of the amount of fluorescence emitted by a sample compared to a reference sample. It is often used in fluorescence spectroscopy to quantify the fluorescence signal from a sample relative to a standard for comparison and analysis.
What compound between phenolphthalein and fluorescein are expected to have the greater quantum yield of fluorescence?
phenolphthalein will have a greater quantum yield because dissolved oxygen can reduce the fluorescence intensity
Si unit for light intensity?
Light intensity is also known as luminosity. Candela is the si unit
What is Si unit of luminous intensity?
In the SI the unit of luminous intensity is candela(cd).
What is the unit of sound intensity measurement?
The unit of sound intensity measurement is the decibel (dB).
What is fluorescence in diamonds?
Fluorescence in diamonds is a natural phenomenon where the diamond emits visible light when exposed to ultraviolet light. This causes the diamond to glow in different colors, such as blue or green. The presence of fluorescence can affect the diamond's appearance and value, depending on the intensity and color of the fluorescence.
What does observation indicate about the source of fluorescence?
Observation of fluorescence can indicate the presence of certain compounds or materials that emit light when exposed to specific wavelengths. By analyzing the color, intensity, and spectral characteristics of fluorescence, scientists can determine the source of the emission, such as organic molecules, minerals, or synthetic dyes.
How does the Stern-Volmer plot illustrate the phenomenon of quenching in fluorescence spectroscopy?
The Stern-Volmer plot shows how the fluorescence intensity of a substance decreases when it is exposed to a quenching agent. This illustrates the phenomenon of quenching in fluorescence spectroscopy, where the quencher molecule reduces the fluorescence emission of the sample by either absorbing the excitation energy or deactivating the excited state of the fluorophore.
What is te SI base unit for luinous intensity?
Intensity is measured in Candela. Candela is its SI unit.
Is intensity the mass per unit volume?
No, the mass per unit volume is density not intensity.
What is the Si of luminous intensity?
The SI unit of Intensity of light is CANDELA.
