A 12.5 g bullet is fired from a rifle. Calculate the speed the bullet needs in order to have a de Broglie wavelength of 3.5 nm.
Consider a 5.44-kg bowling ball rolling at a speed of 16 mph. Find the de Broglie wavelength associated with the bowling ball and explain why is the wave nature of matter insignificant for the bowling ball.
What is the identity of an element with an atom moving at 1% the speed of light with a de Broglie wavelength of 9.5x10-3 pm?
A microscope's maximum resolution is essentially equal to the wavelength of light used to create the picture. Those taken using an electron microscope have a substantially greater resolution—about 0.25 nm in contemporary instruments—than images taken with a photon microscope. What speed must the electrons be accelerated to in order to achieve a resolution of 0.25 nm, assuming that the resolution of an electron microscope is equal to the de Broglie wavelength of the electrons employed?
Calculate the de Broglie wavelength of a 155-g ball traveling at 82 mph. Why is the wave nature of matter not important for this ball?
