A
Compton shift = (h/mc)*[1-cos theta)
Compton Shift = (6.6810^-34/9.1*10^-31*3*10^8) [1-cos 45]
Compton shift = 0.244*10^-11 * 0.292
Compton Shift = 0.07*10^-11 m
B)
Compton shift = (h/mc)*[1-cos theta)
Compton Shift = (6.6810^-34/9.1*10^-31*3*10^8) [1-cos 60]
Compton shift = 0.24*10^-11 * 0.5
Compton Shift = 0.12*10^-11 m
C)
Compton shift = (h/mc)*[1-cos theta)
Compton Shift = (6.6810^-34/9.1*10^-31*3*10^8) [1-cos 150]
Compton shift = 0.244*10^-11 * 1.866
Compton Shift = 455*10^-14 m
SOLUTION :
Line passes through points (-4, -3) and (1, 2)
So, slope of the required line = - (2 - (-3))/(1 - (-4)) = 5/5 = 1
Equation of the required line in point slope form will be :
(y - 2) = 1 ( x - 1)
=> (y - 2) = 1 (x - 1). ANSWER.
Converting it into slope intercept form :
=> y = x - 1 + 2
=> y = x + 1
So, equation of the required line in slope-intercept form :
y = x + 1 (ANSWER).
SOLUTION :
Part A :
Compton shift at an angle 45º :

Part B :
Compton shift at an angle 60º :
= Change in wavelength
= Compton wave length * ( 1 - cos theta)

= 1.215 * 10^(-12) m (ANSWER).
Part C :
Compton shift at an angle 150º :
= Change in wavelength
= Compton wave length * ( 1 - cos theta)
= 0.00243 * 10^(-9) * ( 1 - cos(150))
= 4.534 * 10^(-12) m (ANSWER)
