Refraction of light

• Refraction of light- bending of light waves as they travel from one medium to another.
• $n=$$c/v$This bending of light is associated with the absolute index of refraction of the medium.
• • $n=$$c/v$n=absolute index
  • c=speed of light in a vacuum
  • v= speed of light in the material
• Material INDEX of refraction
