Which of the following best describes reverberation?
A change in the sound wave velocity causes the wave to bend in a different
direction.
The wave fronts become mixed and broken up due to contact with a rough or
irregular surface.
A fraction of the sound waves are absorbed by an object and converted to heat
energy.
A single sound undergoes several reflections due to multiple reflecting surfaces.

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
