What this subsection covers
Phase difference, path difference, linear superposition, constructive and destructive interference, coherence, and the limits of ideal-source models.A strong response uses phase and phasor diagrams 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
Does transmitted intensity follow the ideal angular model over the full measured range?

Does transmitted intensity follow the ideal angular model over the full measured range? Useful evidence includes angle and intensity data, background correction, a fitted model, residuals, uncertainty, and a stated range of validity.

Departments may redistribute weeks, laboratory hours, optics, or the modern-physics survey to match local requirements. 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.
