The Critical Angle Due at the end of Week 5 This week's lab is based on our knowledge of Snell's Law: n1 sin θ1 = n2 sin θ2 and subsequently the critical angle: sin θc = nr/ni Imagine light traveling in these three situations: Water to Air (nwater = 1.33) Glass to Air (nglass = 1.49) And Glass to Water.
Please make a plot of angle of refraction versus incident angle for each of these, and please point out where the critical angle is. Please remember to do the full report here.
