Coherence, phase, and superposition of light

Does a grating's measured ability to separate a close spectral doublet match the resolving power predicted from order and illuminated slit count? Useful evidence includes doublet separation by order, controlled illuminated width, measured resolvance against the ideal prediction, propagated angular uncertainty, and a stated cause for any shortfall.

This GioPhysics course map is an adaptable learning sequence, not academic credit, accreditation, or a universal university syllabus. Third-semester content is the least standardised of the introductory sequence: departments place oscillations, waves, optics, and thermal physics differently, and the modern-physics units here are a bounded survey rather than a complete course in relativity, quantum mechanics, atomic, nuclear, or particle physics. Follow your institution's published scope, notation, laboratory programme, and assessment rules. A result should be checked against units, signs, limiting cases, and the conditions under which its model was derived.
