Talk:A-level Physics/Wave properties/Reflection and Refraction

Specification
From the OCR GCE Physics A specification. Tick with &#10004; when you feel each part of the specification has been covered. Try not to add much more than what is in this list as it would not appear in the exam anyway. Use links to wikipedia for more depth in a topic.


 * 1) Recall the laws of refraction of light.
 * 2) Define refractive index n as Ci / Cr and recall the use of the expression n = sin i / sin r.
 * 3) Describe what is meant by critical angle and total internal reflection.
 * 4) Relate refractive index to critical angle by the equation n = 1 / sin C.
 * 5) Describe the application of total internal reflection to the transmition of light accross an optic fibre.
 * 6) Demonstrate an awareness of the multipath dispersion of a pulse of light in an optic fibre and how, in practice, this problem is overcome.
