What is the name of the index that describes how much light is bent when entering a material?

Player #992008, i am with you all the way. That is why I like this game so much. I might be old, and know lots of stuff, but I still learn things from this game. And, hey, I really like the explanations, too. Just wish the makers would proof a little better.

i love reading the explanations/info supplied after each answer. Great way to teach and to learn.

me, how much do you expect from a free game that uses material from a free encyclopedia? I'm sure you could pay for something that's closer to your standards, if you chose to.

In my lab I am working with refractometer. So this question was so easy for me! 😜

Heartland Old Guy, Cozzy 25, Same here! I too am old but I love this game. I also like the explanations & players’ comments. 😎

That’s how gemstones are classified with their Index of Refraction and clarity the way it is cut.

Hugo, yes, of all the questions that are on here, this was a fantastic for you! 😀😁

Been binge watching Forensic Files for weeks now. This question cannot trick me :)

me, great job proofreading
