1 / 10

For Pair Production to occur, what energy level is required for gamma?

Low energy gamma, around 1 eV range

Moderate energy gamma, around 500 KeV

Very high energy gamma, greater than 2 or 3 MeV

Any energy level

2 / 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?

Outer shells (higher energy levels)

"L" shell (second inner shell)

"M" shell (third inner shell)

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

3 / 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

Particles, which could not exhibit wave-like properties

Neither waves nor particles

Both waves and particles

4 / 10

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

The photon partially loses energy

The photon changes into a neutron

The photon transfers all energy and disappears

The photon splits into two photons

5 / 10

Compton Scattering generally occurs with gamma of what energy range?

Energy range doesn't matter

High energy gamma (high MeV range)

Very low energy gamma (eV range)

Middle energy gamma (low MeV range)

6 / 10

Compton Scattering was first fully explained by which physicist?

A. H. Compton

Isaac Newton

Albert Einstein

Niels Bohr

7 / 10

In Compton Scattering, which electrons are typically affected?

Any electrons except “K” shell

None of the electrons

Only "K" shell electrons

Only "L" shell electrons

8 / 10

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

An electron and a neutron

An electron and a positron

A positron and a neutron

Two electrons

9 / 10

What is the energy transformation result in Compton Scattering?

All of its energy to a positron

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

Part of its energy to a proton

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

10 / 10

What did Compton receive in 1927 for his discovery?

Pulitzer Prize in Literature

Academy Award for Science Communication

Grammy Award for Music

Nobel Prize in physics
