- name refraction when a ray changes path as it passes from air into an optical fibre
- match reflection and refraction labels to the correct wave-behaviour diagrams
3.9 Reflection and refraction question 1
[Maximum number: 1]
This question is about optical fibres.
A ray of light passes from air into a glass optical fibre.
Diagram 1 shows the path of the ray of light after it has passed through the boundary between air and the optical fibre.
State the name of the wave behaviour responsible for the path of the ray of light as it passes from air into the optical fibre.
Refraction.
