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.
Color is measured in several ways, including wavelength relative to the light spectrum, intensity, and purity of tone.bright and dark
A high energy light will have a shorter wavelength than a low energy light. If the wavelength goes down, then the frequency goes up. When calculating energy in the equation, E=hv, frequency (v) is the variable, not the wavelength. So in the equation, if you wanted a more energy (E), you would have the frequency be large. For the frequency to be big, then the wavelength has to be low.
Temperature increases the vibrational energy of atoms and molecules. As a result, molecules vibrate with more intensity and van der waal's forces are broken.

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.
To determine the chemical composition of stars, scientists look at what's called the emission spectrum of the stars, which can be obtained from the light coming from the stars. Thin lines are observed in different parts of the spectrum, which correspond to different chemicals. In other words, the lines are like fingerprints of chemicals. By looking at these fingerprints, one can determine what type of chemicals are present in the star. To determine the surface temperature of stars, we use the Wien's Law. It states that: Peak wavelength x Surface Temperature = 2.898x10-3 Peak wavelength can be determined by looking at the light coming from the star in question. It is the wavelength with the highest intensity.
No. The wavelength of the light determines whether an electron will be ejected from an atom.
Depending on the intensity of the light the thermometer should indicate an increase in temperature.
No object can vibrate at the wavelength of light. wavelength of light depends on the intensity of light and electron movements.
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"?
Examples: frequency, intensity, wavelength.
Intensity is independent of frequency or wavelength. So whether it is Xray or gamma ray both can have the same intensity.
The Wienβs 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.
5 electrons are emitted when calcium is flashed with light of wavelength 340 nm and intensity of 50 percent.
The unit of fluorescence intensity is known as FUs. These are unitless and instead shows the light that is emitted from the longer wavelength.
