    IGCSE Physics Waves & Optics Tutor — Cambridge 0625

    Waves and Optics in IGCSE Physics covers everything from the properties of sound and light to the full electromagnetic spectrum and optical phenomena. Drawing accurate ray diagrams is essential for full marks. Our tutors give you the visual skills and formula fluency to ace this topic.

    Board: Cambridge IGCSE

    Topics Covered

    • Wave properties (frequency, wavelength, amplitude)
    • Transverse and longitudinal waves
    • Reflection of light
    • Refraction and Snell's law
    • Total internal reflection
    • Lenses and ray diagrams
    • Sound waves
    • Electromagnetic spectrum

    Exam Tips

    • Tip 1:Always draw normal lines perpendicular to the surface for ray diagrams
    • Tip 2:Snell's law: n₁sinθ₁ = n₂sinθ₂
    • Tip 3:TIR only occurs when going from denser to less dense medium
    • Tip 4:c = fλ — use consistent units
