Spring 2022 1 30 points You yes you are glowing This is because everything that is at a temperature above absolute zero which is everything gives off electromagnetic radiation light But you re not giving off visible light you re giving off infrared light so we d need to be wearing infrared goggles to see it If your body temperature is 37 C then you re giving off the greatest amount of infrared light at a frequency of 3 2x10 Hz Since your cells are mostly water let s look at one water H O molecule and let s assume that the oxygen atom is mostly staying still and one of the hydrogen atoms is vibrating at this frequency of 3 2x10 3 Hz resulting in this infrared radiation We can model this oscillation as a mass on a spring A hydrogen atom is just a proton and an electron and you can ignore the mass of the electron because it s so small 1 1 6 pts How much time does it take for the hydrogen atom to go through one full oscillation 1 2 8 pts If you re modeling the hydrogen oxygen bond as a spring what is its spring constant 1 3 8 pts Our mass on a spring has both kinetic energy and potential energy For reasons that we won t get into here the total kinetic potential energy on average should be kBT where ka is Boltzmann s constant and T is the temperature What is the amplitude of the oscillation 0 1 4 8 pts What is the hydrogen atom s maximum speed while it is oscillating
