3 Questions
In what year were X-rays discovered and by whom?
X-rays were discovered by Wilhelm Conrad Roentgen in 1895.
What are the properties of X-rays?
X-rays have very short wavelengths, ranging from about $10^{-8}$ to $10^{-12}$ meters, and very high frequencies, ranging from about $3 \times 10^{19}$ to $3 \times 10^{16}$ hertz. They are used to capture human skeleton defects, travel in a straight line, do not carry an electric charge, can travel in a vacuum, and have a shorter wavelength of the electromagnetic spectrum. X-rays, being electromagnetic waves, can be refracted, reflected, diffracted, and polarized.
How do X-rays work?
X-rays use a form of ionizing radiation to take images. They are produced when electrons are accelerated or when atoms change their energy levels. X-rays have higher energy.
