Study Notes
Refraction
- Refraction is the bending of light when it passes from one medium to another.
- A medium is a substance or atmosphere that is different.
Rules for Refraction
- The incident ray, refracted ray, and normal all lie in the same plane.
- The incident ray and refracted ray are on opposite sides of the normal line.
- Light bends toward the normal when the speed of light is less in the second medium. If the speed of light is greater in the second medium, the light will bend away from the normal. This is reversed.
Index of Refraction
- Index of refraction (n) is calculated by dividing the speed of light in a vacuum (constant) by the speed of light in a medium.
- n = c / v where c = speed of light (3 x 108 m/s) and v = speed of light in the medium
Examples of refractive indices:
- Medium | Index of Refraction (n)
- ------ | -------- Air/Vacuum | 1.00 Ice | 1.31 Pure water | 1.33 Ethyl alcohol | 1.36 Quartz | 1.46 Vegetable Oil | 1.47 Olive Oil | 1.48 Acrylic | 1.49 Glass | 1.52 Zircon | 1.92 Diamond | 2.42
