Waves
mechanical waves
types
traverse waves
medium vibrates
right angles to direction
crest
rest position
trough
longitudinal waves
rarefation
compression
medium vibrates
parallel to direction
surface waves
along the surface
separating media
up and down
side to side
a disturbance in matter
carries energy from place to place
electromagnetic waves
transverse waves
changing magnetic fields
changing electric fields
transport energy
production
constantly changing fields
