PPT-X-rays

Xrays was discover in 1895 Xray are shone through the body Each kid of tissue lets xrays through differently Xrays are very good at showing up bonesso if you break a bone it will probably be xrayed. Noda and Y Kamide Supervised by Y Muraki brPage 2br Have you ever had an Xray examination at the hospital In 1896 a German physicist W C R57590ntgen astonished people with an image of bones captured through the use of Xrays He had just discovered th AY 17. 10/19/2011. Outline. What is Multi-messenger astronomy?. Photons. Cosmic Rays. Neutrinos. Gravity-Waves. Sample-Return. Outline. What is Multi-messenger astronomy?. Photons. Cosmic Rays. Neutrinos. What Causes Earth’s Seasons. They are caused by Earth’s orbit around the. sun and the way that Earth . tilts. on its axis.. As Earth revolves around the sun, it stays tilted on its axis.. The tilt when summer begins in the Northern Hemisphere is toward the sun. At the same time the Southern Hemisphere tilts away from the sun causing winter in this hemisphere.. Wavelength the size of an atom. Frequencies above UV. Uses of X-rays. Used in airports to examine luggage for the presence of dangerous weapons or bombs or for illegal transit of goods. . used to detect structural deficits or cracks in metal objects such as bridges and aircraft that are likely to be missed by the human eye. The Discovery of Antimatter!. In 1932 Carl Anderson studied cosmic rays using a “cloud . chamber”. . Charged particles produced in cosmic rays would enter the chamber and leave “tracks”. The tracks would bend in circles because the chamber was placed in a strong magnetic field. Presentation by Stacey . Neumann . to 6. th. Graders at STEM Launch. Statement: . Skin cancer is rare.. False: . 1 in 5 Americans will get skin cancer in their lifetime.. Statement: . You can die from skin cancer.. 3D Projections. . -. Perspective and Parallel Projections. Parallel Projections: . . -.

The idea that there is a natural unit of electricity inside the atom was suggested in 1874 by Irishman G.J. . Electromagnetic Radiation. Electromagnetic waves perpendicular waves combing the electric and magnetic fields. . Electromagnetic waves are produced when an electric charge vibrates or accelerates and can travel through empty space or through matter. . Accidental discovery. First radiograph of Mrs. Roentgen's hand. Roentgen received the first Nobel Prize presented for physics in 1901.. Public viewed discovery as a novelty.

Like many important scientific breakthroughs, the discovery of . X Rays. Are electromagnetic radiations having wavelength of order of 1. Are highly energetic radiations which are emitted when energetic electrons are made to incident on a metallic target.. Were discovered by German Physicist W.C. Roentgen in1895..
