Presentation Transcript

  1. Electromagnetic Spectrum – X-Rays Presentation By: Aaron Burger Allison Frank Jonathan Goulet

  2. The Electromagnetic Spectrum X – Rays: Wavelength = 0.1 Ǻ to 100 Ǻ (1 Ǻ = 10-10 m) Frequency = 3 × 1016 Hz to 3 × 1019 Hz

  3. Mathematical Relationship • All electromagnetic waves follow this relationship between wavelength and frequency C = λ x f Speed of Light Wavelength Frequency

  4. Uses of X-Rays • Used in hospitals and by physicians to image bones or teeth of patients and to find foreign objects or cancers • Used in security checkpoints at airports and other places • Also used by astronomers to study distant galaxies and the expansion of the universe

  5. Dangers of X-Rays • X-Rays and other radiation have been linked to increased likelihood of cancer • There are also dangers associated with x-ray exposure for babies and women who are pregnant

  6. History of X-Rays • Discovered accidentally in 1896 by German Physicist Wilhelm Roentgen, for which he won 1901 Nobel Prize in Physics • Used for many other discoveries in physics, chemistry, and medicine since, including many Nobel Prize winners • Several different elements were discovered using X-Rays
