Question
How fast must a 142 - $\mathrm{g}$ baseball travel to have a de Broglie wavelength equal to that of an $\mathrm{x}$ -ray photon with $\lambda=100 . \mathrm{pm} ?$
Step 1
The de Broglie wavelength of a particle is given by the formula: λ = h / p where λ is the wavelength, h is the Planck's constant (6.626 x 10^-34 Js), and p is the momentum of the particle. Show more…
