Question

If light travels 1% times faster in air than in water, what is the n of water? Show your work.

Answer 1

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..
