# Homework Help: Urgent: Refraction

If I was doing a practical on refraction, and I was using Snell's Law, what would the Aim be. Also remember that, the aim can't be to prove Snell's Law.
Thanks everyone. (please hurry this assignment is due tomorrow)

LOL... to measure refractive index probably :)

No no it has to say something about Snell's Law.

How can we tell you what the aim of your experiment is if you don't even describe what you did? What exactly did you do in this experiment?

We calculated refraction and total internal reflection. But that is not the aim. Then we used Snell's Law to find the results for our assignment.
Thanks.............

What do you mean by that? You calculated the angles of refraction and total internal reflection or what? If you calculated them than what did you measure?

### Awsom Guy

I don't get it. I measured the refraction angle and the total internal reflection angle.

Still the only thing that comes to my mind is to calculate the refractive index using Snell's law and the total internal reflection angle. Do you have to plot any graphs?
