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
