Question

For each of the following, note the relationship between n1 and n2 (i.e. if they are equal or which is greater). If a scenario is impossible (for any relationship between the two media), briefly explain why it is not possible.

For each of the following, note the relationship between n1and n2(i.e. if they are equal or which is greater). If a scenario is impossible (for any relationship between the two media), briefly explain why it is not possible.

Explanation / Answer

(A) not possible since n1*sin(theta1) = n2*sin(theta2) if theta2 = 0, then n1 = 0 which is not possible

(B) n1<n2

(c) n1>n2

(D) n1>n2

(E) impossible since n1*sin(theta1) = n2*sin(theta2) if theta is negative, then n1 is negative which is practically impossible

(F) n1 = n2
