48. Referring to Sample Problem 39-4, we see that the fractional change in photon energy is E E 0 E = λ λ +∆ λ = h/mc (1 cos φ ) ( hc/E )+( h/mc (1 cos φ )) . Energy conservation demands that E E 0 = K , the kinetic energy of the electron. In the maximal case, φ = 180 , and we Fnd K E = h/mc (1

Unformatted text preview: cos 180 ) ( hc/E ) + ( h/mc (1 cos 180 )) = h/mc (2) ( hc/E ) + ( h/mc (2)) . Multiplying both sides by E and simplifying the fraction on the right-hand side leads to K = E 2 /mc c/E + 2 /mc = E 2 mc 2 / 2 + E ....
