Basic
Distance between 2 points on a wave
wavelength
waves that need a medium
mechanical
waves bounce off a surface
reflection
frequency x wavelength is what
speed
types of waves that let us see
light waves
amount of waves per second
frequency
waves that travel through empty space
electromagnetic
change direction in a new medium
refraction
if frequency increases and speed stays, what happens
wavelength decreases
medical imaging waves used for babies
ultrasound
highest point of a wave
crest
particles move parallel in waves
longitudal
bending of waves around an obstacle.
diffraction
unit for frquency
hertz
household appliance for cooking uses what waves
microwaves
lowest point of wave
trough
particles are perpendicular ot the waves
transverse
when waves overlap or combine
interference
unit for wave length
meters
waves used on the radio
radio waves
height from rest to crest
amplitude
sounds waves are what type
longitudal
When the interference increases the amplitude
constructive
If a wave travels 300 m/s with frequency 100 Hz, the wavelength is this.
