A student traces the path of a ray of light through a glass prism as shown in the diagram, but leaves it incomplete and unlabelled. Redraw and complete the diagram. Also label on it ∠i, ∠e, ∠r, and ∠D. "
$\angle i = angle\ of\ incidence$
$\angle r = angle\ of\ reflection$
$\angle e = angle\ of\ emergence$
$\angle D = angle\ of\ deviation$
