What this subsection covers
Path difference, bright and dark conditions, fringe spacing, phase, intensity distribution, and small-angle assumptions.A strong response uses intensity-position graphs 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
Where does the far-field single-slit model stop matching measured intensity?

Where does the far-field single-slit model stop matching measured intensity? Useful evidence includes calibrated intensity profiles, slit geometry, model curves, residuals, uncertainty, and a Fresnel-limit discussion.
Limits to state

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.
