What is the de Broglie wavelength associated with a 1000-kg car moving at 25 m/s?

## Answer to relevant Questions

A scientist wants to use an electron microscope to observe details on the order of 0.25 nm. Through what potential difference must the electrons be accelerated from rest so that they have a de Broglie wavelength of this ...A particle in box is constrained to move in one dimension, like a bead on a wire, as illustrated in Fig. 28.16. Assume that no forces act on the particle in the interval 0 < x < L and that it hits a perfectly rigid wall.

If an excited state of an atom has a lifetime of 2.0 x 10-7 s, what is the minimum error associated with the measurement of the energy of this state? (a) The minimum photon energy to create a proton–antiproton pair is (1) more than, (2) the same as, or (3) less than the minimum photon energy to create a neutron–antineutron pair. Explain.
