Below are sample questions representative of the exercises included on this worksheet and related 8.68 Wave Behavior at Boundaries skill assessments:

Problem 1Difficulty: Mastery

A robotics lab wants a window so people in the hallway can watch work inside without hearing as much machine noise. Which system is the best choice?

AA large open window with no seal

BA laminated glass pane in a sealed frame with acoustic panels inside the lab

CA curtain across the opening with no solid barrier

DA mirror covering a hole in the wall

Solution & Explanation:Laminated glass transmits light for visibility, while the sealed frame and interior acoustic panels reduce sound transmission and reflected noise.

Problem 2Difficulty: Mastery

A metallic emergency blanket and a wool blanket can both help keep a person warm, but one mainly works by reflecting thermal radiation. Which one is it, and why?

AThe wool blanket, because all fabric reflects heat better than metal

BThe wool blanket, because dark materials transmit more heat

CBoth work mainly by reflecting exactly the same amount of thermal radiation

DThe metallic emergency blanket, because its shiny surface reflects thermal radiation back toward the body

Solution & Explanation:The shiny metallic blanket is specifically designed to reflect thermal radiation back toward the person.

Problem 3Difficulty: Mastery

A museum wants visitors to see an artifact clearly while reducing bright reflections from overhead lights on the front glass. Which change is most likely to help?

AReplace the front glass with polished mirror metal.

BAdd an anti-reflective coating to the front glass.

CCover the front glass with black paper.

DUse thicker concrete instead of a glass front.

Solution & Explanation:An anti-reflective coating reduces surface reflections while still allowing visitors to see through the glass.
