Which ray diagram demonstrates the phenomenon of absorption? An illustration with a vector pointed right going through an opening in a boundary and splitting into 3 vectors. One up and to the right, one straight and one down to the right. An illustration with a vector pointed right going through an opening in a boundary and turning into a transverse wave on the other side. An illustration with a vector striking a boundary at an angle and a second vector coming off the boundary at the exact same angle.
