If your de Broglie wavelength were 0.50 m, how fast wouldyou be moving if your mass is 68.0 kg? Would you noticediffraction effects as you walk through a doorway? Approximately how long would it take you to walk through the doorway?

Learning Goal: To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light: \ =h/p, where X is the wavelength, p the momentum, and h Planck's constant. X = 1.06×10-34 Submit Correct m Previous Answers -14 As a comparison, an atomic nucleus has a diameter of around 10 m. Clearly, the wavelength of a moving baseball is too small for you to hope to see diffraction or interference effects during a baseball game. Part C Consider a beam of electrons in a vacuum, passing through a very narrow slit of width 2.00 μm. The electrons then head toward an array of detectors a distance 0.9540 m away. These detectors indicate a diffraction pattern,…

Consider a proton, an electron, and a helium nucleus (alpha particle) moving at the same speed v. List their de Broglie wavelengths from largest to smallest.

Assuming that the smallest measurable wavelength in an experiment is 0.650 fm , what is the maximum mass of an object traveling at 815 m⋅s−1 for which the de Broglie wavelength is observable?

The minimum uncertainty Ay in the position y of a particle is equal to its de Broglie wavelength. Determine the minimum uncertainty in the speed of the particle, where this minimum uncertainty Avy is expressed as a Avy percentage of the particle's speed vy Percentage = × 100 % Vy ignored. Number Units 6). . Assume that relativistic effects can be
