Physics Test 3 Exam Questions and Answers Compton effect - Answer--the change in wavelength; depends on scattering angle and not on the wavelength De Broglie wavelength - Answer--describes wave nature of electrons -photons have wave and particle characteristics, all forms of matter must have both -frequency and wavelength can be determined lambda=h/p= h/mv f=E/h Uncertainty Principle - Answer--if a measurement of position of a particle is made with precision deltax and a simult...

Basic reactor theory lesson 1&2 PHYSICS/SCIENCE LATEST EDITION 2024/25 GUARANTEED GRADE A+ Binding energy The energy equivalent of the mass defect; the amount of energy released when a nucleus is formed from its component parts, also the amount of energy that must be supplied to a nucleus to separate it into its components Bohr model A model of the atom proposed by Nobel Laureate Niels Bohr in 1913 that describes the atom as composed of a dense, positively-charged nucleus with electrons orbi...

Carbon dating is possible because: - correct answer c. The specifi c activity of carbon-14 in living organisms is relatively constant through time, but decays after the death of the organism. Which of the following statements is true concerning these radioisotopes? - correct answer Because lamdaB > lamdaA, the parent and daughter will eventually reach the condition of transient equilibrium. Tissue dose from thermal neutrons arises principally as a result of: - correct answer b. ...
