FUN 1 EO: 1.9

1 / 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)

2 / 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

Any energy level

Very high energy gamma, greater than 2 or 3 MeV

3 / 10

Compton Scattering generally occurs with gamma of what energy range?

Very low energy gamma (eV range)

Energy range doesn't matter

High energy gamma (high MeV range)

Middle energy gamma (low MeV range)

4 / 10

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

Both waves and particles

Waves, which could not exhibit particle-like properties

Particles, which could not exhibit wave-like properties

Neither waves nor particles

5 / 10

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

The photon splits into two photons

The photon partially loses energy

The photon changes into a neutron

The photon transfers all energy and disappears

6 / 10

In Compton Scattering, which electrons are typically affected?

Only "K" shell electrons

None of the electrons

Only "L" shell electrons

Any electrons except “K” shell

7 / 10

What is the energy transformation result in Compton Scattering?

Part of its energy to a proton

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

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

All of its energy to a positron

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

Two electrons

A positron and a neutron

9 / 10

Compton Scattering was first fully explained by which physicist?

Isaac Newton

Niels Bohr

Albert Einstein

A. H. Compton

10 / 10

What did Compton receive in 1927 for his discovery?

Pulitzer Prize in Literature

Grammy Award for Music

Nobel Prize in physics

Academy Award for Science Communication
