FUN 1 EO: 1.9

1 / 10

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

The photon partially loses energy

The photon transfers all energy and disappears

The photon splits into two photons

The photon changes into a neutron

2 / 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

Particles, which could not exhibit wave-like properties

Neither waves nor particles

3 / 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

4 / 10

In Compton Scattering, which electrons are typically affected?

None of the electrons

Any electrons except “K” shell

Only "L" shell electrons

Only "K" shell electrons

5 / 10

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

Moderate energy gamma, around 500 KeV

Very high energy gamma, greater than 2 or 3 MeV

Any energy level

Low energy gamma, around 1 eV range

6 / 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?

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

Outer shells (higher energy levels)

"L" shell (second inner shell)

"M" shell (third inner shell)

7 / 10

Compton Scattering generally occurs with gamma of what energy range?

Very low energy gamma (eV range)

Middle energy gamma (low MeV range)

Energy range doesn't matter

High energy gamma (high MeV range)

8 / 10

What is the energy transformation result in Compton Scattering?

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)

Part of its energy to a proton

All of its energy to a positron

9 / 10

What did Compton receive in 1927 for his discovery?

Pulitzer Prize in Literature

Grammy Award for Music

Academy Award for Science Communication

Nobel Prize in physics

10 / 10

Compton Scattering was first fully explained by which physicist?

A. H. Compton

Niels Bohr

Albert Einstein

Isaac Newton
