The electromagnetic (EM) spectrum is the range of all types of EM radiation. Radiation is energy that travels and spreads out as it goes – the visible light that comes from a lamp in your house and the radio waves that come from a radio station are two types of electromagnetic radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet rays, X- rays and gamma rays.

What is the most common method of preparation of X-rays?
Options:
Radioactive decay of the nucleus
Vibration of atoms
Vibration of molecules
Bombardment of metal by high energy electrons
Correct Answer:
Bombardment of metal by high energy electrons
Explanation:
In a normal X-ray machine, X-rays are produced by bombarding cathode rays on radioactive material.
