Key Topic: Atomic physics

Outside of the Earth’s protective atmosphere, the International Space Station (ISS) is exposed to ionizing radiation and electromagnetic radiation. Ionizing radiation has so much energy it can literally knock the electrons out of any atom it strikes – ionizing the atom. In this activity, students will analyze the radiation that could cause problems on the International Space Station.

Students will
  • practice and review atomic physics concepts and equations;
  • apply Planck’s constant;
  • determine the deBroglie wavelength of a proton; and
  • analyze the frequency of photons.
