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.

None of them.
Explanation:
- The third diagram (incident ray and outgoing ray at the same angle) shows reflection.
- The second (ray turns into a transverse wave on the other side) shows transmission/refraction or a mode conversion.
- The first (ray through an opening splitting into several directions) shows diffraction/scattering.
Absorption would be shown by the incident ray losing energy in the material (reduced amplitude) or terminating in the boundary with no equivalent transmitted or reflected ray — i.e., the energy is converted to heat in the medium.
