Waves Review

points in a standing wave that have no vibration due to destructive interference

nodes

Sound waves from a radio generally travel in which medium?

air

the maximum displacement of a particle by a wave is called

amplitude

sounds produced by the interference of sound waves that are used to tune piono strings

beats

interference that increases amplitude

constructive interference

high point of a wave

crest

the speed of a sound wave

depends on the medium

interference that decreases amplitude

destructive interference

the change in direction of a wave when it encounters an obstacle or edge

diffraction

a wave consists of oscillating electomagnetic fields, radiating outward at the speed of light

electromagnetic wave

our eyes detect light only within a range of _____ called visible light

frequencies

The Doppler effect is an observed change in a wave's

frequency

_______ is the inverse of a period

frequency

the combination of two or more waves that results in a single wave

interference

a wave in which particle motion is parallel to wave motion

longitudinal wave

a wave that requires a medium to pass through

mechanical wave

the_______ is the time it takes for one full vibration of a particle in a medium

period

method of adding crests and troughs of interfering waves together to describe a new wave

principle of superposition

the bouncing back of a wave when it meets a surface or boundary

reflection

the bending of waves as they pass from one medium to another at an angle

refraction

waves travel quickly in a ______ because the molecules are closely packed & physically bonded together

solid

a pattern of vibration that resembles a stationary wave

standing wave

a disturbance at the boundary between two media

surface wave

a wave in which a particle motion is perpendicular to wave motion`

transverse wave

If a transverse wave is moving from right to left the individual particles in the medium are moving

up and down

Waves are often caused by

vibrating objects

The________ of a longitudinal wave radiates outward from its source, while the particles vibrate back and forth about their original positions

wave front

the_______ is the distance between two crest of a wave

wavelength
