# Problem: Now, find the angle θ4 shown in the figure in terms of θ1 and α.Express your answer in degrees in terms of θ1 and α.

###### FREE Expert Solution

From the law of reflection on flat surfaces:

$\overline{){{\mathbf{\theta }}}_{{\mathbf{i}}}{\mathbf{=}}{{\mathbf{\theta }}}_{{\mathbf{r}}}}$, where θi is the angle of incidence and θr is the angle of reflection.

From the figure, θi = θ1

and

θr = θ2
