DrG-Physics · Particles & Waves Vol II — Light · SQA Higher Physics revision

The complete master booklet for the wave half of SQA Higher 'Particles & Waves' — covering all four topics in a single integrated revision companion: Spectra · Inverse Square Law · Refraction · Interference.

Twenty fully-worked SQA-style questions, six inline diagrams, complete data sheet, marker-aligned solutions throughout. The booklet runs to over 35 typeset pages.

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

• Foreword and full data sheet (every constant named, with the SQA convention note and the E-ambiguity clarification)

• Four theory chapters with six inline diagrams (energy-level transitions, inverse-square geometry, refraction, total internal reflection, Young's slits, diffraction grating)

• Twenty SQA-style questions, fully worked

• Examiner's Note + Do/Don't pair after every question

• Closing 'Examiner's Masterclass' — ten common pitfalls specific to the wave half (eV→J conversion, plotting I vs 1/d², lines-per-mm to spacing, calculator-in-radians, etc.)

• Editorial typography (Cinzel · Cormorant Garamond · Crimson Pro · Allura signature) on cream parchment

TWO EDITIONS · ONE DOWNLOAD
