Slow motion

Classical Mechanics Level 3

Which of the following is true about light in media?

  • A - The speed of light in a medium isgiven by v = c ∣ n ∣ . v = c\lvert n\rvert.
  • B - The speed of light in a medium is given by v = c / ∣ n ∣ . v = c/\lvert n\rvert.
  • C - The speed of light in a medium is given by v = c . v=c.
  • D - The wavelength of light in a medium is given by λ m = λ air ∣ n ∣ , \lambda_\textrm{m} = \lambda_\textrm{air}\lvert n\rvert, where λ air \lambda_\textrm{air} is the wavelength of the light in air.

your answer is wrong for sure as it is dimensionally wrong .as n itself has dimensions of speed.
