Basis of Quantum Theory

The Compton effect is based on:

• scattering of photons by the tightly bound inner electrons of an atom.

• scattering of photons by the loosely bound, nearly free electrons of a material.

• interference of light waves scattered from electrons.

• the wave-like behavior of electrons.

In the Compton effect:

• an electron emits an X-ray photon.

• an X-ray photon is absorbed by a metal surface and knocks loose an electron.

• an X-ray photon loses energy after colliding with an electron.

• an X-ray photon gains energy after colliding with an electron.

The photoelectric effect:

• verifies that electrons behave like waves.

• involves the interference of light waves that reflect from the surface of a metal.

• is consistent only with the wave theory of light.

• verifies that light behaves as if it is composed of particles.
