Question 1

What is the de Broglie wavelength of an electron (m = 9.11 × 10-31 kg) moving at a velocity of (10% of the speed of light)?
◦ less than 3.9 × 10-12 m
◦ 2.4 × 10-11 m
◦ greater than 1.1 × 10-4 m
◦ 3.3 × 10-8 m

Question 2

An old copper penny has a mass 3 × 1022 times that of a copper atom. Compare the de Broglie wavelength of a penny moving at 0.5 m/s to that of a copper atom moving 104 times as fast. The wavelength for the
◦ copper atom is 3 × 1026 times that of the penny.
◦ copper atom is 3 × 1018 times that of the penny.
◦ penny is 3 × 1018 times that of the copper atom.
◦ penny is 3 × 1026 times that of the copper atom.
