17.2 - properties of mechanical waves Flashcards
1
Q
what is periodic motion
A
any motion that repeats at regular intervals
2
Q
what is a period
A
the time required for one cycle (wavelength)
3
Q
what is a frequency
A
the number of complete cycles in a given time
4
Q
what is wavelengeth
A
the distance between points on waves
5
Q
what happens to the wavelength when you increase the frequency?
A
it decreases
6
Q
what is amplitude
A
the amount of particle vibrations (think volume - distance from rest to crest)
7
Q
the more energy a wave has…
A
the greater the amplitude
