The Heisenberg uncertainty principles Nature is bilateral: particles are waves and waves are particles. The particle aspect carries with it the traditional concepts of position and momentum; The wave aspect carries with it the concepts of wavelength and frequency

26.1 Some important discoveries at the end of the 20th century a. Measured the charge of the cathode rays; b. Make a static electric deflection of the cathode rays; . Measured the charge to mass ratio of the cathode rays;

I. Choose the Correct Answer 1. A particle on a spring executes simple harmonic motion. If the mass of the particle and the amplitude are both doubled then the period of oscillation will change by a factor of
