Reflection/Refraction Flashcards
1
Q
Specular Reflection
A
Light rays are reflected in parallel, caused by a smooth surface.
2
Q
Diffuse Reflection
A
Light rays are scattered/bend in different directions, caused by a rough surface.
3
Q
Law of reflection
A
Angle of incidence is equal to the angle of reflection.
θi = θr
4
Q
Plane mirror
A
A flat, smooth surface from which light is reflected by specular reflection
5
Q
Refraction
A
When light bends at the boundaries of two mediums.
6
Q
Snells law
A
n1 x sinθ1 = n2 x sinθ2
7
Q
Index of refraction
A
A numerical value that represents the ratio between the speed of light in one medium and the speed of light in the other medium.
