Below are sample questions representative of the exercises included on this worksheet and related 12.95 Diffraction, Interference, Polarization, and Color skill assessments:

Problem 1Difficulty: Mastery

In a very low-intensity double-slit experiment, photons arrive one at a time as localized dots, but over many arrivals a fringe pattern builds up. Which model best fits this evidence?

AEach photon splits into two permanent classical half-photons that hit two points at once.

BThe screen creates dark bands after enough heat accumulates.

CInterference requires many photons to collide with each other in midair.

DEach detection is localized, but the probability pattern is governed by interference of wave amplitudes.

Solution & Explanation:Single detections are localized, but the accumulated distribution follows the same interference pattern predicted by superposed amplitudes from the two paths.

Problem 2Difficulty: Mastery

A double-slit experiment uses equal slit illumination at first. Then a neutral-density filter is placed over one slit so that its electric-field amplitude at the screen is half the other slit's amplitude. What happens to the dark fringes?

AThey become perfectly dark, because any 180-degree phase difference cancels light.

BThey turn into single-slit minima only, because amplitude affects slit separation.

CThey become brighter minima, because the unequal field amplitudes cannot cancel completely.

DThey shift by one full fringe, because intensity changes path length.

Solution & Explanation:Destructive interference is complete only when the two fields have equal amplitudes. Reducing one amplitude leaves a nonzero resultant field at former dark fringes, lowering contrast.

Problem 3Difficulty: Mastery

Two coherent light waves of frequency 5.0 x 10¹⁴ Hz reach a point with a time delay of 1.0 x 10^-15 s. What phase relationship does this create?

AA full-cycle delay, so they must interfere constructively.

BA half-cycle delay, so equal-amplitude waves would interfere destructively.

CA quarter-cycle delay, so the phase difference is 90 degrees.

DNo phase difference, because the time delay is very small.

Solution & Explanation:The fraction of a cycle is f delta t = (5.0 x 10¹⁴)(1.0 x 10^-15) = 0.50 cycle. A half-cycle phase difference is 180 degrees.
