FUN 1 EO: 1.9

1 / 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 changes into a neutron

The photon partially loses energy

2 / 10

In Compton Scattering, which electrons are typically affected?

Only "L" shell electrons

None of the electrons

Only "K" shell electrons

Any electrons except “K” shell

3 / 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)

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

"M" shell (third inner shell)

4 / 10

Compton Scattering generally occurs with gamma of what energy range?

High energy gamma (high MeV range)

Middle energy gamma (low MeV range)

Energy range doesn't matter

Very low energy gamma (eV range)

5 / 10

Compton Scattering was first fully explained by which physicist?

Niels Bohr

Albert Einstein

A. H. Compton

Isaac Newton

6 / 10

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

Two electrons

A positron and a neutron

An electron and a positron

An electron and a neutron

7 / 10

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

Particles, which could not exhibit wave-like properties

Neither waves nor particles

Waves, which could not exhibit particle-like properties

Both waves and particles

8 / 10

What is the energy transformation result in Compton Scattering?

Part of its energy to a proton

All of its energy to a positron

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)

9 / 10

What did Compton receive in 1927 for his discovery?

Grammy Award for Music

Pulitzer Prize in Literature

Academy Award for Science Communication

Nobel Prize in physics

10 / 10

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

Very high energy gamma, greater than 2 or 3 MeV

Any energy level

Moderate energy gamma, around 500 KeV

Low energy gamma, around 1 eV range
