Presentation Transcript


  1. What is ‘α’ called? • What is ‘β’ called? • Define the term ‘refraction’ • α = 42o , β = 30o , v1= 7ms-1 and λ1 = 2m. Using Snell’s law, calculate: • a) v2 b) λ2 c) f d) T

  2. Refractive Index Refraction is change in speed (and therefore direction) when waves move from medium to another. Refractive index is the ratio of the speed of waves in one medium to another.

  3. n1 , n2 , n3 , … = absolute refractive index 1n2 = relative refractive index where: Example: If light travels from water to diamond, what would be the relative refractive index?
