Good afternoon! Please help me figure out the mathematics of this simple plane wave question!
1. Homework Statement
2. Homework Equations
n1*sin(theta1)=n2*sin(theta2)
I need help calculating the angle of incidence.
I found the propagation vector for incidence: ki=2*pi / lambda0 = 4 um
n1= 1 since we are given lambda0
I have n2 = 1.5
I know Snell's law is n1*sin(theta1)=n2*sin(theta2)
What vital information am I missing to solve this? I feel like its staring me in the face yet I'm unable to grasp it.
Thanks so much!
