Match experiment or phenomenon with its significance to our modern understanding

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. A Rutherford Backscattering B Photoelectric Effect C Compton Scattering D Blackbody Radiation E Electron Diffraction Massless photons have momentum. The nucleus of an atom takes up only a tiny fraction of the total volume. Energy levels are quantized. Light behaves like a particle with an energy equal to hf. These particles are called photons. Electrons can exhibit wave-like behavior.

Explanation / Answer

A Rutherford Backscattering: The nucleus of an atom takes up only a tiny fraction of the total volume.

B Photoelectric Effect : Light behaves like a particle with an energy equal to hf.

C Compton Scattering : Massless photons have momentum.

D Blackbody Radiation: Energy levels are quantized.

E Electron Diffraction: Electrons can exhibit wave-like behavior.
