Question 129

Multiple Choice

A proton has a speed of 7.2×104 m/s7.2 \times 10 ^ { 4 } \mathrm {~m} / \mathrm { s } . What is the energy of a photon that has the same wavelength as the de Broglie wavelength of this proton? (melectron =9.11×1031 kg,c=3.00×\left( m _ { \text {electron } } = 9.11 \times 10 ^ { - 31 } \mathrm {~kg} , c = 3.00 \times \right. 108 m/s,h=6.626×1034 Js) \left. 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \cdot \mathrm { s } \right)
