Light Flashcards
1
Q
What does a ray diagram do?
A
shows how light travels, including what happens when it reaches a surface
2
Q
What is the incident ray?
A
The angle of the entering ray
3
Q
What is the reflected ray?
A
The angle of the exiting ray
4
Q
When does total internal reflection occur?
A
When the light is passing from a denser material to a less dense material (glass to air)
5
Q
What is specular reflection?
A
a mirror like reflection, following the law of reflection for a smooth surface where all light enters at the same angle and all exit at the same angle)
6
Q
What is a diffuse reflection?
A
Light hitting a rough surface where the incident ray is reflected at many angles rather than just one
