Answer:

n=1,0101

Step-by-step explanation:

considering n as the refractive index, then you can assume that the decrease of the speed, is because of the density of the medium where it's travelling, so we can translate this as :


n=(c)/(v)

if your initial speed is C=100%V , then if it's decrease 1%, you have that V=99%.V (final Velocity)


  1. n=(c)/(v)

  2. n=(100V)/(99V)

  3. n=(100)/(99)

  4. n=1,0101

I hope it helps you..
