Question 1 There are two distinct components to an X-ray spectrum generated by an Xray tube - the braking radiation (Bremsstrahlung) and characteristic lines. The appearances of these two components depend on the nature of the tube and its operating conditions. Describe the features of these components relating them to the mechanisms by which they are produced.
