1. Review Questions a. Inverse square law b. Black body radiation laws: i. Wien’s Law 1. States that the flux of radiation emitted by a black-body reaches its peak value at a wavelength λ max , which depends inversely on the body’s absolute temperature. So Wien’s law states that hotter bodies emit radiation at shorter wavelengths than do colder bodies. ii. Stefan-Boltzmann law 1. States that the energy flux emitted by a blackbody is related to the fourth power of the body’s absolute temperature. The law would state that if a body X has double the temperature of body Y, body X would release 2 4 times more energy than body Y.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
