Detailed list of IB syllabus understandings and related guiding questions
Skills in the study of physics to be developed during this unit: Understand how to accurately measure sound and light intensity to an appropriate level of precision. Construct and interpret graphs using logarithmic scales. Generate data from models and simulations. Identify and extract data from databases. Compare and quote ratios, values and approximations to the nearest order of magnitude
Future Physics Contexts: radio waves in astronomy and spacecraft communications; atmospheric refraction (example: NASA's EM Spectrum Series), spectroscopy (possible extension: resolution of telescopes and diffraction gratings), terraforming Mars, redshift, interstellar travel distance units (SL) and time dilation (HL).
