the highest point of a wave


the maximum distance that the particles of a wave's medium vibrate from their rest position


the bending of waves around a barrier or through an opening


the number of complete waves that pass a given point in a certain amount of time


the unit of frequency, equal to one cycle per second

Constructive interference

the interference that occurs when two waves combine to make a wave with a larger amplitude

Destructive interference

the interference that occurs when two waves combine to make a wave with a smaller amplitude

Longitudinal wave

a wave in which the vibration of the medium is parallel to the direction the wave travels

Mechanical wave

waves that transfer energy through matter


the material through which a wave travels


the amount of time it takes one wavelength to pass a point


the action of a wave bouncing off an object


The bending of a wave as it passes at an angle from one medium to another

Transverse wave

a wave that moves the medium in a direction perpendicular to the direction in which the wave travels


the lowest point of a wave
