Nuclear Medicine Physics test 1 With Complete Solutions

Nuclear Medicine Physics test 1 With Complete Solutions Velocity - answerIs the speed that waves travel through space or matter Distance traveled X is equal to speed times the time equation - answerWavelength=vT 1895, hertz - answerProved that waves moves at speed of light As frequency imoroves, - answerWavelenght decreases and vice-versa The energy carried by an electromagnetic wave is proportional to its frequency ewuation - answerE=h*f, h is planks constant A wave - answerIs the propagation in space of a physical condition or phenomenon In wave motion - answerOnly Energy Propagates (no mass) Mechanical origin - answerSounds waves Electromagnetic origin - answerSatellites, cells, microwaves, Radio waves, light, sun, uv, heat, xrays, gamma rays Physical conditions repeating itself - answerPeriodic waves or cyclical waves Cyclical waves - answerCharacterized by length, frequency, and velocity Wavelength - answerCm. Distance from a point on one wave to the same point on another wave Frequency - answer(F) CYCLE/SEC. number of wave formeations, cycles, per unit of time Period (t) - answerAmount of time it takes to make one complete cycle Characteristics of stabke nuclei - answer-some are unstable even in ground state -not all combinations of protons and neutrons produce stable nuclei -radioactive decay, unstable nucleus emits particle and, or photons to transform itself to more stable nucleus -all heavy nuclides are unstable - the lighterthe nuclides, the more stable -stable nuclide favor even # -stable nuclides are clustered around an imaginary kine called line of stability Nuclear binding energy - answerMass of atom compared to sum of mass of individual components such a proton, neutron, and ele
