Answer true or false: Light waves are longitudinal waves but sound waves are transverse. Sound waves can travel through a vacuum. a. True b. False True or False: For a transverse wave: The pulse's displacement is always to the north. Indicate true or false in the following stat...

When a sound wave travels, the air molecules oscillate in the same direction in which the sound waves propagate. Hence, sound waves are longitudinal waves.
Sound is a mechanical disturbance that propagates through a medium and is capable of being detected by the ear. It is produced by vibrations that cause the medium to oscillate back and forth, creating a wave that travels through the medium. The speed of sound in a medium depends on the pr...
Longitudinal (compression) waves made by vibrating matter Sound Waves 15.2 Sound Waves A sound wave is a wave of alternating high-pressure and low-pressure regions of air. Sound waves need a medium to travel Sound travels faster through denser mediums Does sound travel faster through water or ...
False True or false. Intensity is an acoustic variable. False True or false. motion of particles in the wave is an acoustic variable. True True or false. Density is an acoustic variable. True What are the units of a pressure measurement of an acoustic wave?
Sound is produced by vibrations Sound is a compression(longitudinal) wave Sound compresses particles together, then expands them causing compressions and rarefactions….like a speaker pushing and pulling particles together and apart Sound requires a medium (solid, liquid, gas) in order to be heard...
aDiffraction of light on a longitudinal acoustic wave in a glass material is provided by the P11 photoelastic constant, if light is polarized along the sound propagation direction, or P12 constant for an orthogonally polarized beam. The figure of merit M2 of the material is different for the tw...
