Waves Flashcards
1
Q
How are waves caused?
A
disturbances in the medium that transfer without a net
2
Q
What are the 2 types of waves?
A
transversal, longitudinal
3
Q
how do particles move in waves?
A
move left and right (longitudinal) or up and down(transversal). The particles do not move all the way across
4
Q
What are longitudinal waves?
A
… . . . . … . . . . … . .
(the line)
particles move left and right to make rarefaction and compressions.
5
Q
What are rarefactions
A
areas of a wave with low density (few particles)
6
Q
What are compressions
A
areas of a wave with high density (many particles)
7
Q
What are transverse waves?
A
’’’–…–’’’–…–’’’–…–’’’–…–’’’
(squiggly line)
particles moving up and down
forms amplitude, crests, troughs, wavelengths, equilibrium
