The foam materials within a music recording studio have the unique property of acoustic absorption, whereas they take in energy from sound waves as opposed to reflecting the wave back into the room. Which answer properly describes the use of the foam?

The foam reduces unwanted sounds within the recording studio.

The foam has some benefit, but is mostly there for decorations within the studio.

The foam specializes in deflecting the sound waves into other directions.

The foam increases the amplitude of the sound waves so they travel out of the recording studio.

What aspects of reduced kinetic energy design will a sound engineer include in an environment, in order to reduce the impact of unwanted noise? Choose three (3) correct answers .

construct walls of soft materials in order to absorb kinetic vibrations of sound

design wide, open spaces so the kinetic vibrations move away and into the distance; at the same time allowing other sounds to move in

minimize kinetic energy transfer by designing walls with plenty of curtains to capture surface area vibrations

include living plants in the environment which absorb kinetic vibrations of sound

incorporate hard, environmental surfaces to reflect the kinetic vibrations until their volume decreases

Which statement best explains the difference between longitudinal and transverse wave patterns?

Particles in longitudinal waves travel in the direction of the wave, while particles in transverse waves travel perpendicular to the wave.

Longitudinal waves have troughs, while transverse waves have crests.

Longitudinal waves produce energy, while transverse waves consume energy.

Particles in longitudinal waves travel perpendicular to the wave, while particles in transverse waves travel in the direction of the wave.

Waves were created on three identical ropes. Of the three waves shown, Wave 2 has the greatest:

frequency, because there are more crests in the same length of rope than there are in the other waves

wave speed, because it has more crests than the other ropes

frequency, because it has a larger wavelength than the other ropes

wave speed, because the rope is moving up and down faster than the other ropes

An air traffic controller monitoring radar signals determines that an aircraft is flying at the wrong altitude. She communicates with the airplanes pilot via radio to alert them of this. What kind of wave plays a role in air traffic control and why?

radio waves because they are lower wave frequencies that require less energy and can travel through the atmosphere

gamma waves because these wave frequencies are so high that they can pass through any matter

visible light waves because these wave frequencies allow the aircraft pilot to always see the flight route ahead
