Hey all.

I'm doing a science lab on graphing angles of incidence and refraction but I'm struggling with a couple of things.

I'll type the question out here: "Draw a graph of θi versus θR. Use the same scale on your vertical and horizontal axis. Is this graph a straight line? Answer your question in bold on the bottom of the graph."

I'll also provide a table of the angles at the bottom of the post.

Basically what I'm wondering how I would graph this. Like, what would I use for my x and y axis as well as would I be drawing two or one line?

This is what I have so far:

how i read the bolded is that you are to create one graph with theta-i on one axis and theta-r on the other, your table giving the co-ordinates for the points

Well a night of work, coffee and classical music later and I finished the lab. This really helped me, thanks a lot.

yw & good to get some positive feedback
