DrG-Physics · Spectra · SQA Higher Physics revision

Higher Physics revision on emission, absorption, and continuous spectra plus energy-level transitions. Five SQA-style questions fully worked.

A focused single-topic revision companion on Spectra for SQA Higher ‘Particles & Waves’ (the wave half — Volume II — Light). Covers continuous, emission, and absorption spectra, with quantised energy-level transitions and the photon-frequency relationship.

The DrG-Physics revision companion is not a worksheet. It is a structured exam-thinking guide — built around the way an SQA marker reads your script. Each worked solution leads with the relationship the examiner is looking for, substitutes cleanly, and evaluates with units. Every question carries a marker-aligned command-word tag (CALCULATE · 2 marks · STATE + JUSTIFY) so students learn what kind of answer earns each mark.

WHAT’S INSIDE:
• Theory chapter on the three types of spectra and quantised atomic energy levels, with a clear hydrogen-like energy-level diagram showing emission and absorption transitions
• Five SQA-style questions covering the three spectrum types, photon energies from level transitions, max and min photon energies, why each element has a unique fingerprint, and wavelength from energy
• Special focus on the eV-to-joule conversion that’s the single biggest source of lost marks on this topic
• Examiner’s Note after every question naming the typical pitfall
• Do/Don’t pair to reinforce SQA marking conventions
