Ray Diagrams Flashcards
1
Q
Ray DIagram
A
A way of modelling what happens when light is reflected or refracted
2
Q
Normal
A
A line drawn at 90 degrees to the barrier or mirror
3
Q
The law of reflection
A
When waves are reflected, the angle of incidence is equal to the angle of reflection
4
Q
Refraction
A
When a ray of light changes its direction as it enters a different material, usually caused by a change of speed as it enters the new material
5
Q
Total internal reflection
A
When the angle of incidence increases so much that the angle of refraction completely reflects inside the glass
6
Q
Critical angle
A
The angle of incidence during total internal reflection
