What this subsection covers
Light rays, wavefront normals, specular and diffuse reflection, law of reflection, plane mirrors, and model scale limits.A strong response uses ray 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
Which focal length and thin-lens assumptions are supported by object-image measurements?

Which focal length and thin-lens assumptions are supported by object-image measurements? Useful evidence includes object and image distances, a linearized or nonlinear fit, residuals, uncertainty, and aberration observations.

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.
