A bullet is fired from a rifle. The end of the barrel is a circular aperture. Is diffraction a measurable effect?
A) Yes.
B) No, because only subatomic particles have de Broglie wavelengths.
C) No, because a circular aperture never causes diffraction.
D) No, because the de Broglie wavelength of the bullet is too large relative to the aperture.
E) No, because the de Broglie wavelength of the bullet is too small relative to the aperture.

Question

Quizplus · Accepted Answer

The de Broglie wavelength of a macroscopic object like a bullet is extremely small compared to the size of the barrel's aperture, making diffraction effects negligible and unmeasurable.
