Episode 316: Preparation for Reflection and Refraction Topic
These activities, from the Institute of Physics, give an overview of reflection and refraction. The emphasis is on an interpretation in terms of waves. Applications, particularly those involving total internal reflection, are considered.
The series of learning episodes include:
Episode 317: Reflection and refraction of waves
Episode 318: Total internal reflection
Following study of this topic, students should: 1. know how to justify the law of reflection by a wave diagram 2. know how to justify Snell’s law in terms of wave velocities 3. be able to perform calculations involving the refractive index 4. be able to perform calculations involving critical angle 5. know the benefits of fibre optic communication.
