Match the speed of sound with the correct medium:

Air = 330 m/sec Water = 1480 m/sec Muscle = 1580 m/sec Bone = 4080 m/sec

Match the term with its definition:

Compression = A local increase in pressure Rarefaction = A local decrease in pressure Frequency = The number of compressions or rarefactions per unit time Wavelength = The distance between successive compressions and rarefactions

Match the medium with the relative speed at which sound travels through it:

Solid = Fastest Liquid = Relatively slower Gas = Slowest Elastic material medium = Sound propagates through

Match the variable with its corresponding representation in the speed of sound formula $v_s = f\lambda$:

v_s = Speed of sound f = Frequency \lambda = Wavelength 1/T = Frequency of a wave Signup and view all the answers

Match the description with the correct concept:

Sound wave = A pattern of disturbance caused by energy Mechanical disturbance = Propagation through an elastic material medium with definite velocity Wave transfer = Energy without transferring matter Equilibrium = State disturbed by sound Signup and view all the answers

Match the mathematical representation with its concept:

f=1/T = Frequency of a wave \lambda = c/f = Wavelength of a sound wave v_s = f\lambda = Speed of sound \lambda = Wavelength Signup and view all the answers

Match the phenomenon with its appropriate description:

Compression = Local increase in pressure Rarefaction = Local decrease in pressure Propagation = Movement of vibrations through a medium Disturbance = Caused by energy traveling away from the source Signup and view all the answers

Match the type of wave with its characteristics:

Sound wave = Vibration through a medium in the form of a mechanical wave Energy wave = Transfers energy without transferring matter Mechanical wave = Disturbance from equilibrium through an elastic medium Vibration = Propagation through solids, liquids, or gases Signup and view all the answers
