Physics Review Question Unit: Waves Year: 1994 Question#: 36 Question: An acceleratong particle that does not generate electromagnetic waves could be? (1 ) A neutron (2 ) A proton (3 ) An electron (4 ) An alpha particle What is this question really asking? Explanation by: Tiffany L (no last names) [ Return to question menu ] Answer 1 A neutron CORRECT Waves are generated by accelerating electric charges. Of the particles listed only a neutron, does not generate electromagnetic waves, because it has no charge. return to top Answer 2 A proton INCORRECT A proton has a positive charge, and it generates electromagnetic waves when moved. return to top Answer 3 An electron INCORRECT An electron generates electromagnetic waves when moved, because it has a negative charge. Answer 4 an alpha particle INCORRECT An alpha particle consists of two protons and two electrons, since it has a charge, then it could generate electromagnetic waves when moved. return to top What's this question really asking? Which one of these choices, does not generate an electromagnetic wave? return to top |
