Music studios use "soundproof" recording rooms. The walls of these rooms are designed in such a way that the only sounds that reach the microphones inside the room are sounds from inside the room. The most important characteristic is designing the soundproof room is to create walls that -
allow communication between people inside and outside the room
reflect sounds around the room to alter their properties
allows sounds to move easily from one place to another
absorb sounds and prevent them from passing through
Which of the waves is carrying the greatest amount of energy?
This table provides simplified data on the relationship between the amplitude of a wave and the energy the wave carries.

Students are modeling waves by shaking a rope up and down. We know this is a wave because-
The rope is made up of strands of cotton threads which are braided together
It has a repeating pattern with a specific wavelength, frequency and amplitude
the rope stops moving when the students stop shaking it up and down
the student can change the distance the rope moves by moving the rope further up or down
Waves of energy made by vibrations

Which of the following provides an example of sound waves being reflected?
hearing music being played by a neighbor's stereo through a wall
Water in a glass vibrating because of the sound of thunder
A noise that produces an echo when it bounces off a distant wall
The sound of a distant train getting louder as it approaches an observer
Automobile engineers create quieter cars and trucks by designing acoustic glass that does all of the following EXCEPT-
diffuses sounds
reflects sounds
absorbs sounds
amplifies sounds
A ringing bell makes noise inside a glass jar. Then the air is removed from the glass jar using a vacuum pump. When all of the air leaves the jar, the sound of the ringing bell can no longer be heard. Which of the following best explains why the students can no longer hear the bell?
Remove the air from the jar allow the bell to ring only very softly.
The air in the jar provides a medium for the sound to travel through.
The sounds in the empty jar is reflected off the inside of the glass sides.
The difference in pressure inside and outside the glass jar is too great.
Geologists can learn about rock layers beneath the surface of Earth using sound waves. They use a vibration truck to send sound waves into the ground. A measuring truck has special microphones, called geophones, that pick up sounds. This method for learning about rock layers depends on what characteristic of sound waves?
Sound waves can travel through and reflect off rock layers
Sound waves require energy, such as electricity to generate them
Sound waves can travel for an unlimited distance from the source that creates them
Sound waves are absorbed by dense solids and reflect off liquids
