Refraction |
When a ray of light travelling from one medium to another and bends from its original direction. |
|
|
Incident ray |
The ray of light travelling in the first medium. |
|
|
Refracted ray |
The ray of light travelling in the second medium. |
|
|
Angle of Incidence |
The angle between the incident ray and the normal. |
|
|
Angle of Refraction |
The angle between the refracted ray and the normal. |
|
|
Normal |
The perpendicular line drawn at the point of incidence. |
|
|
Refractive Index |
The ratio of velocity of light in air (vacuum) to the velocity of light in the given medium. Denoted by "m". |
|
|
Prism |
A transparent refractive medium bound by two plane surfaces making an angle with each other. |
|
|
Angle of deviation |
The angle between the produced incident ray and the produced emergent ray. It is denoted by the Greek symbol "𝛿" or "delta".
|
|
|
Dispersion |
The process of splitting of a white light into its constituent colours. |
|
|
Monochromatic Light |
Light of only one colour (Of one wavelength). |
|
|
Polychromatic light |
Light with different colors (different wavelengths) A.K.A White light or Compound light. |
