How fast does a proton have to be moving in order to have the same de Broglie wavelength as an electron that is moving at 5.20 × 106 m/s?
1. (A) Find the de Broglie wavelength (in nm) associated with an electron that is moving with a velocity of 2310 km/s. The electron rest mass is 9.11 x 10-31 kg. Note, electrons having this speed would need to be treated as waves in atoms because the wavelength is on the order of the size of atoms. (B) A baseball weighs 220 g. Top speed for a professional pitcher is about 100 mph when he throws a fast ball. Find...
