Use de Broglie wavelength and matter waves

Paper 1, Paper 2 5 marks Difficulty 5

de Broglie wavelength from momentum

A particle in a mass defect calculation has momentum \(2.8\times10^{-24}\,\text{kg m s}^{-1}\). Calculate its de Broglie wavelength in nm. Use the diagram labels before calculating the requested value. Enter the numerical result and choose the interpretation that matches the quantum or nuclear physics.
