Making waves
A disturbance in matter that transfers energy through the matter
mechanical waves p 300
this is a waves maximum displacement of the medium from its rest position for a
amplitude p 305
this is a type of longitudinal wave you can hear
soundwave p 309
any speed that is faster than the speed of sound in the medium of interest
an indication of how high or low a sound is, which is primarily determined by the frequency of the sound wave
pitch, p321
a wave in which the medium vibrates perpendicular to the direction the wave travels
transverse wave p 301
this indicates the how many wave crests there are per second
frequency p 305
this membrane in our ear vibrates when sound waves reach it
tympanic membrane p311
this happens when an object reaches and surpasses the speed of sound
sonic boom p 314
t/f sound waves with low pitch have high frequencies
false p 321
a wave in which the medium vibrates parallel to the direction the wave travels
longitudinal wave p302
the distance between a point on one cycle of a wave and the same point on the next cycle
wavelength p 306
t/f temperature does not affect sound speed
false p 312
the rate at which a wave's energy flows through a given area
intensity p315
a change in sound frequency caused by the motion of the sound source, motion of the listener, or both
doppler effect p 323
a wave that travels along the surface of a medium
surface wave p303
t/f wavelength and frequency are inversely proportional to one another
true p306
which is faster light or sound?
light p 313
unit used to measure sound
decibels dB p 316
what are at least 2 ways sonar is used and name one animal that uses sonar
volcanoes, ocean bats
ocean waves are a type of this wave
surface wave p303
this is wavelength x frequency
speed p307
what types of mediums does sound travel fastest through, solid, liquid or gas?
solid p 313
physical response to the intensity
what are ways ultrasonic waves are used
ultrasound, medicine p 325
