Suppose you graphS i n open parentheses theta subscript 1 close parenthesesVs.S i n open parentheses theta subscript 2 close parenthesesand get a slope m = 0.413. If the second material is air (n2 = 1.0003), use equation 2 in the manual to calculate n1.
n1 = 1
n1 = 2.42
n1 = 1.46
n1 = 1.47
n1 = 1.49
n1 = 0.413
