Below are sample questions representative of the exercises included on this worksheet and related 12.128 Wave Particle Duality skill assessments:

Problem 1Difficulty: Mastery

An atom emits a photon, the photon passes through a diffraction grating, and later one detector pixel records the event. Which sequence of models is most appropriate?

AWave-like emission only, with no localized detection

BParticle-only propagation through the grating, so no wavelength matters

CNuclear fission at the grating followed by sound-wave detection

DParticle-like emission and detection with wave-like propagation through the grating

Solution & Explanation:Emission and detection are quantized, localized events. The diffraction grating requires wave-like propagation and interference based on wavelength.

Problem 2Difficulty: Mastery

A beam of electrons is tightly collimated before a diffraction experiment. The collimation narrows the position range but increases spread in transverse momentum. Which model idea is most relevant?

ACollimation removes all de Broglie wavelength from electrons

BMomentum spread proves electrons have become photons

CA wave-based quantum description is needed because localization and momentum spread affect diffraction

DDiffraction can be predicted without considering wavelength or momentum

Solution & Explanation:Quantum wave descriptions connect spatial localization, momentum spread, and diffraction. This is beyond a simple classical-particle path model.

Problem 3Difficulty: Mastery

Which setup most cleanly demonstrates both wave and particle aspects of electrons without requiring many electrons to be in the apparatus at once?

AA high-current wire and an ammeter only

BA low-intensity electron source, a double slit, and a position-sensitive detector that records one hit at a time

CA charged balloon next to a wall

DA hot metal block cooling in air

Solution & Explanation:A low-intensity double-slit setup can ensure that electrons pass one at a time. Each event is localized, while many events build an interference pattern.
