The fast-moving electrons stopped by a heavy metallic target in an evacuated glass tube, give rise to the production of:
Correct answer: B. X-rays
- A. α- particles
- B. X-rays
- C. Laser
- D. β- particles
Explanation
'X-rays' are commonly produced in X-ray tubes by accelerating electrons through a potential difference (a voltage drop) and directing them onto a target material (i.e. tungsten). The incoming electrons release X-rays as they slow down in the target (braking radiation or bremsstrahlung).

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
