X-rays Flashcards
1
Q
Bragg’s Equations
A
1] normal incidence:-
bsin$=n₹
2] glancing incidence:-
2dsin@=n₹
3] $+@=180
where:
₹-lambda
2
Q
Compton shift
A
^₹= h/m•c * (1-cos@)
where:-
h/m•c = 0.024 A
3
Q
Kinetic energy of recoil electron
A
E-W
4
Q
Direction of recoil electron
A
tan@ = ₹sin@/(₹•-₹cos@)
₹-wavelength
5
Q
Mosleys Law
A
Root of frequency is closely related to the atomic number
(f)^0.5 = n(Z-€)
€–> sigma
f–> frequency
For K-alpha line €=1
For L-alpha line €=7.4
