Below are sample questions representative of the exercises included on this worksheet and related 8.74 Wave Based Technologies in Everyday Life skill assessments:

Problem 1Difficulty: Mastery

Which statement best connects ultrasound imaging, wireless communication, and active noise reduction?

AAll three technologies depend on predicting how waves travel and interact with materials or other waves

BAll three technologies use only visible light waves

CAll three technologies work only in outer space

DAll three technologies depend on stopping every wave from reflecting

Solution & Explanation:Ultrasound, wireless systems, and noise-reduction devices all rely on understanding wave behavior such as reflection, absorption, transmission, and interference.

Problem 2Difficulty: Mastery

A rescue drone loses its live Wi-Fi video when it flies behind a thick concrete wall. Which solution is most likely to help?

ATurn the camera light off so the radio waves move faster

BCover the drone with metal foil

CPut the relay antenna where it has a clearer line of sight to the drone

DLower the drone into water to improve transmission

Solution & Explanation:A clearer path reduces blocking and weakening of the signal, which is important for strong real-time wireless video.

Problem 3Difficulty: Mastery

A music venue offers foam earplugs and active noise-canceling earbuds. Which recommendation is best for a drummer exposed to sudden very loud hits?

AActive noise cancellation alone, because it is always best for sudden peaks

BNo protection, because drums create only low-frequency waves

CFoam earplugs or other strong passive protection, because sudden sharp sounds are harder for active systems to cancel

DInfrared headphones, because light blocks sound directly

Solution & Explanation:Passive protection reduces a wide range of sounds immediately, including sudden peaks that active systems may not cancel well.
