Question

The momentum of a particle of wave length 1 angstorm is

Answer 1

Explanation:

At non-relativistic speeds, the momentum of a particle is equal to its rest mass, m, multiplied by its velocity, v. The unit of the de Broglie wavelength is meters (m), though it is often very small, and so expressed in nanometers (1 nm = 10(-9) m), or Angstroms ( ).
