The following data is provided for the spectral distribution of the radiation emitted by a diffuse surface.

  • Elambda (W/m2 micrometer) = 0 for lambda between 0 and 5
  • Elambda (W/m2 micrometer) = 100 for lambda between 5 and 10
  • Elambda (W/m2 micrometer) = 200 for lambda between 10 and 15
  • Elambda (W/m2 micrometer) = 100 for lambda between 15 and 20
  • Elambda (W/m2 micrometer) = 0 for lambda above 20

Provide the following:

  1. A plot of Elambda versus lambda, based on the given data
  2. Assumptions
  3. Total emissive power, E
  4. Total intensity of the radiation emitted, Ie
  5. Explain the reason why there are (or there are no) differences between the intensity emitted at 0 degrees versus at 30 degrees to the surface normal direction. Use a sketch and only one sentence.

Why is it that thermal radiation of a black body usually described by a spectral distribution...
Why is it that thermal radiation of a black body usually described by a spectral distribution function rather than an intensity vs frequency curve? I have a vague explanation for this: Any measured intensity of radiation will contain a spectrum of frequencies which are impossible to separate (even with a very good spectrometer, one can only measure the intensity of an interval). So it is practically impossible to assign a particular intensity to a particular frequency. Is my reasoning correct?

The spectral absorptivity of a large diffuse surface is ????=0.850 for ??<1???? and ????=0.25 for ???1????. The bottom of the surface is well insulated, while the top may be exposed to one of two different conditions. (a) In case (a) the surface is exposed to the sun, which provides an irradiation of ????=1200 W/m2, and to an airflow for which T = 300 K. If the surface temperature is Ts =320 K, what is the convection coefficient associated with the...

Electromagnetic radiation is emitted by accelerating charges. The rate at which energy is emitted from an accelerating charge that has charge q and acceleration a is given by dE/dt=q^2a^2/6πϵ0c^3 where c is the speed of light. PartA: If a proton with a kinetic energy of 6.3 MeV is traveling in a particle accelerator in a circular orbit with a radius of 0.650 m, what fraction of its energy does it radiate per second? PartB: Consider an electron orbiting with the...

In the Bohr model, the Paschen series of spectral lines is caused by radiation absorbed or emitted as an electron transitions between the 2nd excited state and any higher excited state (3rd excited state and higher) of the hydrogen atom. The Paschen series spectral lines all involve infrared photons. a) Using the Bohr model, calculate the energy of the electron when it is in the 2nd excited state, in units of electron-Volts (eV). b) Calculate the energy of the electron...

Short pulses of microwave radiation are emitted from the Crab nebula at a distance L from the earth. When they reach the earth, the frequency components of the pulses are dispersed after a travel time T, such that waves of different frequencies arrive at different times. The observed dispersion is due to the intervening interstellar plasma, which enables us to estimate the electron density of this plasma. Assuming one knows L by other means, obtain the expression for the electron...

Consider the blackbody radiation emitted at a temperature of 500◦C. (i) Explain why a tungsten wire in an old-fashioned light-bulb starts to glow as it becomes sufficiently hot. (ii) Calculate the percentage pressure increase of the blackbody radiation if the temperature is raised to 550◦C. An electron escapes the hot tungsten wire and is subsequently trapped in a one-dimensional square quantum well. The potential outside the well can be approximated as infinite. (iii) Sketch the probability distribution of the electron...
