- 1Refraction DefinitionRefraction is the bending of light as it passes from one medium to another medium of different density.
- 2Law 1 of RefractionThe incident ray, normal and refracted ray are all in the same plane.
- 3Law 2 of RefractionSnell's Law
- 4Refractive index of a mediumThe refractive index (n) of a medium is the ration of sine i to sine r when a light travels from a vacuum to that medium.
- 5EXPERIMENT: Verification of Snell's Law of RefractionShine a light box through glass prism. Note angle of refraction/ incidence.
Graph it.
sin i on y-axis
sin r on x-axis
All values of n are equal - 6aNwRefracted index from air to water
- 7Formulas for refractive indexor
- 8Real and apparent depthn= real depth
-------------
apparent depth - 9EXPERIMENT: Refractive Index of a LiquidPin in water and out of cork, mirror
No parallax
Depth of beaker= Real depth
y- axis real depth
x- axis apparent depth - 10Critical AngleOnly happens if we ave light going from dense to less dense
- 11Total Internal ReflectionThe optical phenomenon is when light is reflected back from a boundary between 2 media: it occurs when the light travels towards the less dense medium from the denser one, striking the boundary with an angle of i greater than the critical angle for those two media
- 12EXPERIMENT: Measurement of focal length of converging lensFinding image
Measure f, u and v
Use lens formula
