Waves/Sound
refers to how waves bounce off an object and change their direction of travel
Reflection.
occurs when the direction of a wave changes because of a change in medium
Refraction.
a disturbance that transfers energy from one point to another
wave.
the lowest point of a transverse wave
troughs.
the height of the wave from its trough or crest to its midpoint, is a measure of the wave's intensity.
amplitude.
the number of waves per second (cycles per second) with respect to frequency
hertz.
highness or lowness of a sound, depends on the frequency of the sound waves.
pitch.
sound waves must travel through this in order to transfer energy.
medium.
the highest point of a transverse wave.
crest.
an area where paticles in a medium are pushed together by a wave's energy
compression.
a compressional wave produced by vibrations in matter
sound wave.
the difference in the loudness of sound
volume.
the movement of particles by a wave.
vibration.
the distance between wave crests and troughs.
wavelength.
What activity do you do 5,000 times a day?
breathe.
a reflected sound wave
echo.
units of measure using volume of sound
decibels.
a wave that moves matter up and down as it travels through a medium.
transverse wave.
a measure of how many wave crests or troughs pass a given point in one unit of time.
frequency.
What part of your body has the most bones?
hands.
Scientists use these devices to study waves
oscilloscopes.
the pitch of a sound can seem to change if its source or listener is in motion.
Doppler effect.
a wave that moves matter back and forth as it travels through a medium.
longitudinal wave
an area where particles in a medium are spread apart by a wave's energy.
rarefaction.
What is the weakest of your five senses?
taste.
