Refractive Index = sin <i/sin<r


Note: Trust at all times was one of the noblest feelings experienced by man. On the level of trust in society as a whole, universal freedom, civilization and development directly depends. This is, beyond all doubt, the same standard to which people should strive throughout the world. All people, no matter how similar they may seem at first glance, will always remain different.
