|
Thin Lens Equation |
1/do + 1/di = f |
Think of the relationship between do, di, and f |
|
|
Snells Law |
N1 × sin (theta 1) = N2 × sin (theta 2) |
Find the angle of refraction, using the index of refraction (n) and the angles. |
|
|
Magnification Equation |
M = hi/ho OR M = - (di/do) |
Can be solved using either ho and hi, or do and di. |
|
|
Incident Ray |
The ray which comes from the light source, hitting the normal. |
First |
|
|
Reflected Ray |
After hitting the normal, the ray comes off the other side, at the same angle the incident ray hit. |
Reflection |
|
|
Refraction |
The phenomena where light slows down speed when traveling from one medium to another. This causes the angle of refraction to be different than the angle of incidence. This is called refraction. |
<R =/= <I |
|
|
Normal |
The line where the incident ray hit the surface of a medium. Represented with a dotted line. |
On the surface of the medium. |
|
|
Total Internal Reflection |
Occurs when the angle of refraction is over 90°, and causes reflection to occur instead of refraction. |
When Refraction = Reflection |
