An Electron Has the Same De Broglie Wavelength as the Wavelength

question 76

Multiple Choice

An electron has the same de Broglie wavelength as the wavelength of a $1.8 \mathrm { eV }$ photon. What is the speed of the electron? ( $m _ { \text {electron } } = 9.11 \times 10 ^ { - 31 } \mathrm {~kg} , c = 3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , 1 \mathrm { eV } = 1.60 \times 10 ^ { - 19 } \mathrm {~J}$ )

• A) \(840 \mathrm {~m} / \mathrm { s }\)
• B) \(980 \mathrm {~m} / \mathrm { s }\)
• C) \(770 \mathrm {~m} / \mathrm { s }\)
• D) \(1100 \mathrm {~m} / \mathrm { s }\)
• E) \(910 \mathrm {~m} / \mathrm { s }\)
