Using planck's law determine the wavelength of maximum emission intensity for blackbody with a temperature of 6000K?
Use the formula Lamdamax*T = b Where b is Wein's constant, 2.898 x 10^-3 m K you get Lamdamax = 4.97 X 10^-7 m this wavelength represents UV light.
What is the relationship between the color of the star and temperature of a star?
The color of a star is related with the wavelength of the light observed. Wien's Law states that: Peak Wavelength x Surface Temperature = 2.898x10-3 Peak Wavelength is the wavelength of the highest intensity light coming from a star.
What happens if you place a thermometer in any wavelength of visible spectrum?
Depending on the intensity of the light the thermometer should indicate an increase in temperature.
Can an object vibrate at the wavelength of light?
No object can vibrate at the wavelength of light. wavelength of light depends on the intensity of light and electron movements.
Is there any completely incoherent light?
It's not clear exactly what you mean by "completely incoherent." Blackbody radiation is given off at any angle and any phase, but the shape of the intensity/frequency curve is determined by the temperature; is that close enough to "completely incoherent"?
What is two properties of sound?
Examples: frequency, intensity, wavelength.
Does the intensity of Xrays and gamma rays differ?
Intensity is independent of frequency or wavelength. So whether it is Xray or gamma ray both can have the same intensity.
Human body temperature is about 310 K 98.6 degree F At wavelength do humans radiate the most energy What kind of radiation do you emit?
The Wien’s law for maximum intensity is, Here, is the wavelength of maximum intensity and T is the temperature of human body. Rearrange the above expression for . Substitute for T to find . So the maximum energy is radiated at 9355.83nmK. Humans emit infrared off radiation which is electromagnetic radiation with a frequency lower than visible light.
How many electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent?
5 electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent.
What is the unit of fluorescence intensity?
The unit of fluorescence intensity is known as FUs. These are unitless and instead shows the light that is emitted from the longer wavelength.
What are the things that can be measured about waves?
Speed, wavelength, frequency, period, amplitude, intensity.
What wavelength of maximum intensity does the Sun emit?
The Sun emits most of its radiation in a wavelength band between 0.1 and 4.0 micrometers (µm).
