Question

light waves are completely absorbed by the wall.light waves are completely absorbed by the wall.the wall absorbs most of the light waves. the small amount that transmits through is only enough to see a shadow.

Explanation:

The scenario shows that the person on one side of the wall cannot see the drummer on the other side, which matches the description that light waves are fully absorbed by the wall (so no light transmits to allow visibility). The other option mentions some light transmitting to see a shadow, which does not align with the visual where the person cannot perceive the drummer at all.

Answer:

Light waves are completely absorbed by the wall.
