Light: Reflection, Refraction and Total Internal Reflection

Learning outcomes

• Explain total internal reflection, calculate critical angle sin c = 1/n, and describe optical fibre applications.(analyze)
• Construct ray diagrams for thin converging lenses to form real and virtual images.(apply)
• Apply law of reflection i = r, Snell's law n = sin i / sin r, and refractive index n = c/v.(apply)
