Question
Lab Exercise 2: Blackbody Radiation and Radiative Equilibrium 100 points total. 3 points per question, except the last one is 4 points For this lab, you will first use an interactive online simulator of blackbody radiation to study the relationship between the temperature of an object and the amount and type of electromagnetic (EM) radiation that it emits. Then, you will use another simulator to study the effect of planetary albedo, distance from the sun, and surface temperature orn the energy budget of a planet. Our overall goal is to explain the relationship between the radiative equilibrium temperature of a planet and these different variables Directions: Submit your answers as a DOC or an uploaded PDF (preferable). Please number your answers. Include units for all numerical values (that have units). To make it easier to type, you can express exponents using the symbol. For example, 5.67 x 10A- 8 W mA 2 KA-4. Use complete sentences for "Why" and "Explain"-type questions Please complete the readings and quiz for the week before you do this assignment, so that you have had practice with some of the equations. I recommend keeping Lectures 2-3 and 2-4 handy, since you will be referring to them Be sure to include units for all valuesExplanation / Answer
1. The Wavelength for maximum emmision from sun is 500 nm.
2. It is visible EM radiation.
3. Just mention the diferrence between the value calculated in lecture 2.3 and 500 nm and comment on that.
4. Now the curv is dissappeared, the scale is not suitable for the radiation curve, as it will have a maximum emission somewhere outside the range of the x axis and the scale of y axis would also be changed.
5. According to Wiens's law the maximum wavelength for this temperatue is 11.4 micrometer.
6. This is infrared portion of spectrum.
7. 4 times.
8. 9 times.
9. The total emmision of radiation is 5.670373*10^-8*255^4 or 239.76 W/m^2
10. The ratio is 255^4/5778^4 or 0.009394
11. 9 times
12.
