• Sound waves are absorbed by the wall, and visible light waves are transmitted through the wall.

• Sound waves are transmitted through the wall, and visible light waves are reflected by the wall.

• Sound waves are reflected by the wall, and visible light waves are refracted by the wall.

• Sound waves are reflected by the wall, and visible light waves are absorbed by the wall.
