Hi can I get help with this. Based on the observation table, there needed to be a graph made for sin theta incidence on x axis and sin theta r on the y axis. From that I just want to ensure if I got the slope right. I calculated it to be around 1.1. Can you also explain what the slope of this graph of the line tells us, reference any relevant equations for it, I feel it has something to do with snells law.Using the slope, can you help me determine the index of refraction of a lucite because that is what I used for this lab. There is a procedure written you can see that to get a gist of what the lab was about.What sources of error were present in the lab? How could you improve this lab?Finally, what conclusion could be made for this lab.Thank you:)

Refraction Lab Problem : Determine the index of refraction of glass / lucite Variables . - Manipulated . - Responding : - Controlled ( 2 ) : Materials , laser, lucite block , paper, protractors / rulers Procedure 1 Draw outline of block on white paper 2 Draw an incident light ray 3) shine light that is aligned with the line drawn ( incident ray ) on the first surface 1 Track where light went in the block , ensure you hold the laser steady 5) Change the incident angle , measure the refracted angle . (6) Do this for 7 different manipulations (7) connect the 2 lives,only care for the angle at the surface Observations : Changing angle of Incident Ray VS Angle of Refracted ray Bi incident Or Refracted Sin bi Sin Or angle Angle 50 127 0 . 77 0. 45 14 40 0, 69 0, 4 4 40 35 0. 64 35 22 0. 57 0 . 37 30 20 ' 10. 50 0. 3 4 27 15 0, 45 22 0. 37 0 . 17
