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

"Light of wavelength 0.527 µm (in air) enters the water in a swimming pool. The speed of light in water is 0.700 times the speed in air. What is the wavelength of the light in water?"

2. Relevant equations

v = c /n, where n = 1.33 ,the index of refraction

3. The attempt at a solution

The wavelength of light in air is given. [tex]\lambda[/tex]=0.527

I looked up the speed of light in air -- 299704644.54 m/s

I also know that the speed of light in water is 0.700(299704644.54)

I am not sure how to relate these numbers to v = c/n though, or the equation to use to find the [tex]\lambda[/tex] of light in water. Can anyone offer any insight? Thanks!
