Listen to the recording of someone yelling in a tunnel. Why do we hear something after each yell?

• Sound waves are striking the walls of the tunnel and bouncing off of the walls.

• Sound waves are striking the walls of the tunnel and going into the walls (they are not passing all the way through).

• Sound waves are striking the walls of the tunnel and going all the way through the walls.

• Sound waves are striking the walls of the tunnel and being bent as they go through the walls.
