Question

What are the approximate energies of the Kα and Kβ x rays for copper?

a) (8.05 , {keV}) and (8.90 , {keV})
b) (7.20 , {keV}) and (7.85 , {keV})
c) (6.45 , {keV}) and (7.00 , {keV})
d) (9.15 , {keV}) and (9.80 , {keV})

Answer 1

The approximate energies of the Kα and Kβ X-rays for copper are (8.05 keV) and (8.90 keV) respectively, which matches option (a).

Step-by-step explanation:

The approximate energies of the Kα and Kβ X-rays for copper can be determined by using the known values from physics reference materials or databases.

According to the provided information, the energies of the Kα and Kβ X-rays for copper are EKα = 8.00 keV and EKβ = 9.48 keV, respectively. Therefore, the correct answer for the approximate energies of the Kα and Kβ X-rays for copper is (8.05 , keV) and (8.90 , keV), which corresponds to option (a).
