SP3f Ray diagrams Flashcards
1
Q
What is the law of reflection?
A
angle of reflection = angle of incidence
2
Q
What happens when the angle of incidence equals the critical angle?
A
the refracted light passes along the boundary.
3
Q
What happens at angles of incidence greater than the critical angle?
A
the light is completely reflected inside the block.
4
Q
Total internal reflection?
A
reflection of a ray of light inside a medium such as glass/water when it reaches an interface. Only happens when angle of incidence inside the material is greater than the critical angle.
