X-Rays with a Wavelength Of $0.00100 \mathrm {~nm}$ Are Scattered by Free Electrons At

question 56

Short Answer

X-rays with a wavelength of $0.00100 \mathrm {~nm}$ are scattered by free electrons at $130 ^ { \circ }$ from their original direction. What is the kinetic energy (in $\mathrm { keV } )$ of each recoil electron? ( $m _ { \text {electron } } =$ $\left. 9.11 \times 10 ^ { - 31 } \mathrm {~kg} , c = 3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , 1 \mathrm { eV } = 1.60 \times 10 ^ { - 19 } \mathrm {~J} , h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \cdot \mathrm { s } \right)$
