Waves and Energy

4PH1 Topics 3-4. Mark-scheme Q&A on waves, EM spectrum, refraction, sound, energy transfers and electricity generation. Spec-complete, Paper 1+2 tagged.

Full description:
This 54-slide interactive revision deck covers the full content of Topics 3 and 4 of the Pearson Edexcel International GCSE Physics (4PH1) specification.

Sections covered:

1. Properties of Waves (spec 3.1-3.7) - PAPER 1
2. Doppler Effect and Wave Behaviour (spec 3.8-3.9) - PAPER 1
3. The Electromagnetic Spectrum (spec 3.10-3.13) - PAPER 1
4. Light: Reflection and Refraction (spec 3.14-3.22) - PAPER 1
5. Sound Waves (spec 3.23-3.29P) - PAPER 2 §
6. Energy Stores and Transfers (spec 4.1-4.5) - PAPER 1
7. Thermal Energy Transfer (spec 4.6-4.10) - PAPER 1
8. Work, Power and Energy Resources (spec 4.11-4.19P) - PAPER 2 §

Every section contains: topic divider, question slides, mark-scheme-standard answer slides, and a Red-Amber-Green checkpoint.

The deck also includes:

• Command word trainer (8 physics-specific command word examples)
• Named practicals summary (refraction investigations, refractive index, thermal energy transfer, speed of sound)
• 8 examiner watch-outs specific to waves and energy topics
• Gap analysis table
• “How this deck works” guide

Calculations covered: wave speed, refractive index and critical angle, kinetic energy, gravitational potential energy, work done, power, efficiency.
