What two wave interactions happen when a wave hits a barrier?
i
The return of a wave to the medium for which it came when it hits a barrier?
It is reflection.
When a sound wave bends around a barrier so you can still hear the sound even though you cant see the source the wave has undergone what?
The sound wave has undergone refraction.
What is the term for the area of wave compressions produced by sounds from object moving faster than the speed of sound?
sound barrier
The amount of diffraction that occurs when a sound wave encounters a barrier depends on the waves?
diffraction wavelength

i
What has to happen for a sound wave to happen?
For a sound wave to be created there has to be a vibration
What word can precede wave barrier and bite?
sound
Qhat is the term for the area of wave compressions produced by sounds from an object moving faster than the speed of sound?
sound barrier
What happens to an ultrasound ray when it hits a boundary?
First off, Ultrasound is not a ray. Like all sound, its a wave. Ultrasound simply means its so low in pitch, its below the human hearing range.When a sound wave hits a barrier, two things happen. The energy from the wave is partially absorbed into the barrier itself, which will now vibrate with that energy. Also, some of the energy from the wave is deflected, or bounced off.Think of it as being how you can hear someone talk through a wall. Even though the sound waves are bouncing off the wall, and therefore a small room like a closet would amplify the sound, its still being transferred through the wall.

What must happen for a sound wave to form?
sound
What would happen to a sound wave if the energy increased?
It becomes louder. The amplitude of the sound wave increases
