(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Light of wavelength 559nm in vacuum passes through a piece of silica (index of refraction 1.437). Find the speed of light in silica. Answer in units of m/s

2. Relevant equations

Index of Refraction = Speed of Light in Vacuum/Speed of Light in Substance

[n = c/v]

3. The attempt at a solution

Manipulate: [n = c/v] ---> [cn = v]

Plug in: (5.59 * 10^-7) (1.437) =(8.03 * 10^-7)I converted 559nm to (5.59 * 10^-7) meters

It seems like a simple enough problem, but my answer is incorrect! =(
