Sound - .......🔷ANSWERS🔶......✔✔ Vibratory energy transmitted by pressure waves through a
medium
Resonance - .......🔷ANSWERS🔶......✔✔ The natural tendency for an object to vibrate with great
amplitude at one frequency than at others when a driving force is applied
Frequency - .......🔷ANSWERS🔶......✔✔ Number of complete compression-rarefaction cycles per
second

and rarefactions
Wavelength - .......🔷ANSWERS🔶......✔✔ The distance between one wave crest or trough to the next

apart
Complex Wave - .......🔷ANSWERS🔶......✔✔ Acoustic combination of several different pure tones
present simultaneously
Resonant frequency - .......🔷ANSWERS🔶......✔✔ The frequency at which an object vibrates with
the greatest amplitude

is exposure to contaminated substances via food, water, blood, or bodily fluids
Indirect Contact Transmission - .......🔷ANSWERS🔶......✔✔ Occurs when an infected person or
object touches a surface and the another person touches that surface
