VOCABULARY 1
A WAVE THAT OCCURS WHEN THE PARTICULES OF A MEDIUM move parallel to the direction of the wave( back and forth motion )
longitudinal wave
height or strength of a wave
amplitude
the horizontal line that passes exactly in the middle between the waves crest and trough (sometimes called the rest period)
midline
in the paper cup telephone activity, why did the system NOT transmit sound if the string was not pulled tight?
the string was too loose, so it couldn't transmit any vibrations
how the sound would be heard if it has a high frequency
high pitch
a rapid movement of an object back and forth
vibration
a distance between one peak and the next on a wave
wavelength
lowest point of a wave
trough
the video about the glitter and the speaker- what was the relationship between the glitter movement and volume? 2 answers
the lower the volume, the less glitter moves
the higher volume, the more the glitter moves
how the sound would be heard with a low frequency
low pitch
a wave that occurs when the particles of a medium are displaced perpendicularly to the direction of the wave (up and down motion)
transverse wave
the number of cycles a wave completes in a period of time
frequency
highest point of a wave
crest
how the sound would be heard if it has a high amplitude
high volume
a solid,liquid, or gas that a wave can travel through
medium
how the sound would be heard if it had a low amplitude
low volume
