Question

You have a frustrating day and just feel like screaming; you grab a pillow to scream into it. Which interaction of sound would take place here, (reflection, refraction or absorption), and how did the sound waves move? PLEASE HURRY!!!!!!

Answer 1

PLEASE HURRY

Answer 2

I think that the answer is ...
ABSORPTION !!!!! The friendly local fluffy pillow would absorb the sound of the scream. Hence the sound would be MUFFLED. The sound waves moved by air particles, and then pillow particles moving backwards and forwards along the direction of travel. (A longitudinal wave). Presumably, the bits in the pillow are "harder" for the sound wave to move backwards and forwards, and so they take up energy from the SCREAM, and that energy doesn't get heard by anyone who's not listening, so to speak.
However, as the sound travels its happy, possibly loud, way, some will echo off the pillow, or be reflected. But the surface being all irregular would mean that the echo would be muffled.
When the happy sound wave hops from the air to the material inside the pillow, there will be some change of medium. That should also give rise to some refraction, I think.
Overall, though, I think the answer is absorption (shhhhhhh !)
