What is the de Broglie wavelength for a proton (m = 1.67× 10−27 kg) moving at a speed of 9.50 × 106 m/s? (h = 6.63 × 10−34 J⋅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...
