Scope & orientation

What this subsection covers

Counter-propagating superposition, nodes, antinodes, boundary conditions, resonant modes, frequency spectra, and preparation for optical cavities and waveguides.

A strong response uses phase and phasor diagrams and states where the model stops being reliable.

Reasoning checklist

Evidence, assumptions and limits

01

Assumptions to state

State the system, observable, approximation, and conditions held fixed before using a model.

02

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.

Limits to state

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.
