Q: What does IP Physics Notes (Upper Secondary, Year 3-4): 8) Waves cover?
A: Review EM spectrum properties, mechanical wave terms, sound/ultrasound, and CRO measurements for IP Year 3-4.
Quick recap -- Waves transport energy without carrying matter. Understand the language (wavelength, frequency, period), track phase with wavefronts, and apply the same maths from microwaves to ultrasound echoes.
Keep your practice loop tight via our IP Physics tuition hub-it links each topic here to quizzes, diagnostics, and WA-style problem sets.
