Week 25:  4 March to 8 March 2024

4 March 2024:

In Class:  Relationship Between Velocity and Wavelength:

  • ν = f λ
  • v = velocity or speed
    f = frequency
    λ = wavelength

    •   Absolute Index of Refraction:

  • n =   c
     ν 
  • n = absolute index of refraction
    c = speed of light in a vacumm
