A room inside a recording studio is lined with soft foam in order to absorb the energy of sound waves produced inside the room. How will sound waves interact with the foam? A. The foam will refract the waves, causing their frequency to change
B. The foam will take up some of the waves' energy, decreasing their amplitude
C. The foam will cause constructive interference, increasing the waves' amplitude.
D. The foam will reflect the waves, causing an echo.

It's B

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
