Question details

4a (10 pts) In Chapter 3, we learmed about two fundamental radiation laws Stefan-Boltzmann Law quantfies the power emitted by one square meter P (Wim2) of a substance with temperature 7 P oT., where σ :567 x 104 w(m2 K4) is the Stefan-Boltzmann constant Wiens Law quantifies the wavelength of maximum emission mas (um) of a substance of temperature T ax CIT, where C-2897 um K is iens constant Both of these equations require that T is expressed in Kelvin (another SI unit for temperature). Thus, we must become familiar with converting temperatures to Kelvin. 1 Convert the following temperatures T given in the first column of the table below from Celsius (°C) to Kelvin (K). Write your converted temperatures in the appropriate blank spaces in the third column of the table. When appropriate, round your answers to two decimal places. Then, compute the corresponding values of power per square meter P for each T that you calculated. Write your answers for P in the appropriate blank spaces in the fourth column of the table. When appropriate, round your answers to two decimal places. You may use the conversion provided below to perform the calculations by hand, or you may use an accurate online converter of your choice.

Homework #1 4b. (1 pt) Compute the below, rounding to two decimal places For the human body, max wavelength of maximum emission Amax (um) for the normal body temperature you computed in (4a). Write your answer in the blank space Hm (1 pt) Circle the name of the category in the following list that the wavelength out, all of the of maximum emission you calculated in (4b) falls into. (Note: As it turns above example s from (4a) fall in this category of radiationl) Gamma X-ray Ultraviolet Visible Near infrared Thermal infrared Microwave Radio
