Any energy level

Low energy gamma, around 1 eV range

Very high energy gamma, greater than 2 or 3 MeV

2 / 10

What did Compton receive in 1927 for his discovery?

Grammy Award for Music

Nobel Prize in physics

Academy Award for Science Communication

Pulitzer Prize in Literature

3 / 10

In Compton Scattering, which electrons are typically affected?

Only "K" shell electrons

Any electrons except “K” shell

None of the electrons

Only "L" shell electrons

4 / 10

In the Pair Production process, what is the transformation result of all the photon's energy?

A positron and a neutron

Two electrons

An electron and a neutron

An electron and a positron

5 / 10

Compton Scattering generally occurs with gamma of what energy range?

High energy gamma (high MeV range)

Very low energy gamma (eV range)

Energy range doesn't matter

Middle energy gamma (low MeV range)

6 / 10

Compton's explanation of photons was initially rejected because it was thought that photons exhibited which properties?

Waves, which could not exhibit particle-like properties

Both waves and particles

Neither waves nor particles

Particles, which could not exhibit wave-like properties

7 / 10

In the context of a photon transferring all of its energy to an electron and ejecting it, which shell is the electron almost always from?

"L" shell (second inner shell)

Outer shells (higher energy levels)

"K" shell (inner shell - lowest energy level)

"M" shell (third inner shell)

8 / 10

Compton Scattering was first fully explained by which physicist?

A. H. Compton

Niels Bohr

Albert Einstein

Isaac Newton

9 / 10

What is the energy transformation result in Compton Scattering?

Part of its energy to a proton

All of its energy to a positron

Part of its energy to an electron (binding energy + kinetic energy = beta particle + lesser energy photon)

All of its energy to an electron (kinetic energy only)

10 / 10

What is the primary characteristic of the photon in a photoelectric effect?

The photon splits into two photons

The photon transfers all energy and disappears

The photon partially loses energy

The photon changes into a neutron
