Specic Goals: F2.'l I can use appropriate terminology related to quantum mechanics and special relativitY F22 I can solve problems related to the photoelectric effect, the Compton effect. and de Broglie's matter waves F23 I can solve problems related to Einstein's theory of special relativity in order to calculate the effects of relativistic motion on time, length. and mass F24 I can conduct a laboratory inquiry or computer simulation to analyse data that support a scientific theory related to relativity or quantum mechanics Instructions 1. 2. 3. 4. Choose three situations to analyse. Decide which principle(s) apply and why. Solve for as many unknowns as you can. Explain in sentences how you performed the problem. Make sure your explanation is thorough and does not leave any room for confusion or ambiguity. Problems 1. A spacecraft is travelling at 0.7c relative to Earth. An astronaut onboard shines a ashlight out ahead of the spacecraft. A particle at rest takes 2.32 x mil-6 s to decay. Relative to the laboratory's frame of reference in which it moves, the particle decays in 3.90 x 10-6 5. A muon travels 5090 m in its lifetime, as measured by an observer on Earth. From the muon's reference frame. that distance measures 653 m. Electromagnetic waves of a wavelength 250 nm are angled towards a calcium plate. The maximum kinetic energy of electrons from a tungsten surface is 1.3 eV. An X-ray photon behaves like a particle with momentum equal to 1.93 x 1DA-24 kg'mis
