X rays of wavelength 0.0100 nm are directed in the positive direction of an x axis onto a target containing loosely bound electr
Fofino [41]

Answer:

a)  =4.84*10^{-12}

b)= -2.76*10^{-14} J

c)i.e -2.76*10^{-14} J

d)= 0 and the direction of motion is equal to zero

Explanation:

a) compton shift

\Delta\lambda = \frac{h}{mc} (1-cos\theta)

\Delta\lambda = \frac{6.626*10^{-34}}{9.11*10^{-11}3*10^8} (1-cos180)

                        =4.84*10^{-12}

b) the new wavelength

\lambda' = 10.0*10^{-12} +4.84^10^{-12}

               =14.84*10^{-12} m

\Delta E = E' - E

              =hc[\frac{1}{\lambda'}-\frac{1}{\lambda}]

\Delta E = 6.626*10^{-34}*(3*10^8)[\frac{1}{14.84*10^{-12}}-\frac{1}{4.8*10^{-12}}]

= -2.76*10^{-14} J

C)By conservation of energy, the kinetic energy of recoiling electron is equal to the magnitude of energy between the photon energy

i.e -2.76*10^{-14} J

d) the angle between the positive direction of motion

sin\phy = \frac{\lambda_t sin\theta}{\lambda'}

            =\frac{2.43*10^{-12}sin180}{14.84*10^{-12}}  

             = 0

the direction of motion is equal to zero.
