What this subsection covers
Sinusoidal wave functions, the wavelength-frequency-speed relation, medium dependence, dispersion, group-versus-phase-speed intuition, and calculus-ready interpretation.A strong response uses interference and standing-wave patterns and states where the model stops being reliable.
Reasoning checklist
Evidence, assumptions and limits
Assumptions to state
State the system, observable, approximation, and conditions held fixed before using a model.
Evidence to collect
How do path and phase differences determine the measured interference pattern?

How do path and phase differences determine the measured interference pattern? Useful evidence includes calibrated positions, phase or path differences, intensity data, predicted extrema, residuals, uncertainty, and a coherence limitation.

This GioPhysics course map is an adaptable learning sequence, not academic credit, accreditation, or a universal university syllabus. Departments may redistribute weeks, laboratory hours, optics, or the modern-physics survey to match local requirements. Thermal physics appears as an unnumbered institutional extension: some universities assess it within Physics II, while others teach it in a separate course, so include the thermal extensions only where the local syllabus requires them. A result should be checked against units, signs, limiting cases, and the conditions under which its model was derived.
