Question $21(1$ point$)$

In a Compton scattering experiment the incoming X ray of $3\mathrm{.}4$MeV is scattered off weakly bound electron in the thin carbon target at the angle of $60$o$.$ The recoiling electron hits the metal mesh behind the target causing a secondary X ray to be emitted.

A$)$ Find the wavelength of the X$-$ray scattered of the electron.

B$)$ What is the maximum energy of the secondary X ray? Enter this answer into the box below.

State your answer in MeV to the nearest $0\mathrm{.}01$ MeV.

Take mass of the electron to be me $=9\mathrm{.}11*10-31$ kg$=0\mathrm{.}511$MeV$/$c$2$
