Answer:

n=1,0101

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 :

[tex]n=\frac{c}{v}[/tex]

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

  1. [tex]n=\frac{c}{v}[/tex]
  2. [tex]n=\frac{100V}{99V}[/tex]
  3. [tex]n=\frac{100}{99}[/tex]
  4. [tex]n=1,0101[/tex]

I hope it helps you..
