This problem uses Snell's law given by:

$\overline{){{\mathbf{\eta}}}_{{\mathbf{1}}}{\mathbf{s}}{\mathbf{i}}{\mathbf{n}}{{\mathbf{\theta}}}_{{\mathbf{1}}}{\mathbf{=}}{{\mathbf{\eta}}}_{{\mathbf{2}}}{\mathbf{s}}{\mathbf{i}}{\mathbf{n}}{{\mathbf{\theta}}}_{{\mathbf{2}}}}$

From this, we can formulate the equation:

A ray of light traveling through air encounters a 1.5cm -thick sheet of glass at a 43 degree angle of incidence. Assume n = 1.5.

How far does the light ray travel inside the glass before emerging on the far side?

d=?

Answer should be in cm
