## Homework Statement

A monochromatic plane wave with wavelength 500µm is propagating through a dissipative medium with refractive index 1-0.0002i. It approaching the edge of the medium, and will pass out into free space. If the angle of incidence is not 90°, how much will the wave deflect as it passes out into free space?

## Homework Equations

Snell's Law:

## The Attempt at a Solution

The refractive index of free space would be 1-0*i so so far I have 1-0.0002i/1. But I don't know how to find the angles.
