Production and use of X-rays — practice question

Electrons in a beam move at high speed through a vacuum. They strike a metal target, which leads to the emission of X-ray radiation. Fig. 7.1 shows how the intensity I of the emitted X-ray radiation varies with wavelength $\lambda$.
(a)[3]

Explain why the wavelengths are distributed continuously.

(b)[3]

Explain why there are narrow peaks of increased intensity at certain wavelengths.
