What is the temperature if the peak of a blackbody spectrum is at 14.0nm ?
What is the temperature If the peak of a blackbody spectrum is at 17.0 m? What is the wavelength at the peak of a blackbody spectrum if the body is at a temperature of 1700 K? About 0.1ev is required to break a "hydrogen bond" in a protein molecule. Calculate the minimum frequency and maximum wavelength of a photon that can be accomplish this minimum frequency
The spectrum of a blackbody has a peak wavelength of 5.30×10-7 meters. What is its temperature, in kelvins?
An opaque object that emits a thermal radiation spectrum is called a “blackbody”. As the temperature of a blackbody increases, what happens to the peak wavelength of the light it radiates?
A glowing blackbody is at a temperature of 4.325×103 K. For this temperature the peak in the intensity vs. wavelength curve occurs at a wavelength of 670 nm. When the temperature of the blackbody changes, the peak shifts to 1.876×103 nm. What is the new temperature of the blackbody?
The universe is filled with thermal radiation, which has a blackbody spectrum at an effective temperature of 2.7 K. What is the peak wavelength of this radiation? What is the energy (in eV) of quanta at the peak wavelength?
The illustration shows the spectrum of electromagnetic radiation emitted by a blackbody at two different Kelvin temperatures. The range of visible frequencies (those that can be detected by the human eye) is also shown. (a) No matter what the value of the Kelvin temperature T, the spectrum decreases to zero at very high frequencies. Why is this? (i) At very high frequencies the photon energy is very small compared to kT. (ii) At very high frequencies the photon energy is...
The cosmic background radiation permeating the universe has the spectrum of a 2.7-K blackbody radiator. What is the peak wavelength of this radiation? The constant in Wien's law is 0.0029 m ∙ K. Hint: the answer will be in mm

Construct plots that show the wavelength-dependent energy spectrum of a blackbody at a temperature of 5800 K (approx. temperature of the Sun) using both the Planck distribution and the Raleigh-Jeans distribution. Confirm agreement between the two at long wavelength. a. What is the maximum emission wavelength at this temperature? b. What is the total power output (W/m^2) ? c. Using the Planck distribution, estimate what fraction of the Sun's total power output is emitted in visible wavelengths (400-750 nm)
