Transmission and Absorption

Most rooms have hard flat walls. However, music studios have soft, foam-like material on them. Studios use these materials to prevent...

• sound waves hitting the walls from bouncing back.

• sound waves hitting the wall from staying in the walls.

• sound waves hitting the wall from passing all the way through them.

• sound waves hitting the wall from bending.

Why does the arrow appear to change direction as water is poured into the glass? You can try this experiment at home.

• Light waves are bouncing as they pass through air, glass and water.

• Light waves are traveling in a straight line as they pass through air, glass, and water.

• Light waves are not passing through the air, glass, and water.

• Light waves are bending as they pass through the air, glass, and water.
