question

The group velocity of light in a certain substance is found to vary inversely with wavelength. How does the index of refraction vary with wavelength?

physics

options

  1. n = [λ / (a + bλ^2)]
  2. n = λ^2 / (a + b)
  3. n = λ / (a - bλ^2)
  4. n = (a + b) / λ
  5. n = (aλ^2) - (b / λ)
  6. n = (aλ^2) / (1 + bλ)
  7. n = (a - bλ) / λ^2
  8. n = 1 / (aλ + bλ^3)
  9. n = 1 / (a + bλ^2)
  10. n = a + bλ
