Question

Match experiment or phenomenon with its significance to our modern understanding of physics. Only choose each experiment once, and choose the experiment that best matches the statement.

E. Electron Diffraction

ABCDE The nucleus of an atom takes up only a tiny fraction of the total volume.
ABCDE Light behaves like a particle with an energy equal to hf. These particles are called photons.
