a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium
Wave
the physical environment through which the wave passes
Medium
a wave that requires a medium through which to travel
Mechanical Waves
a wave that consists of oscillating electric and magnetic fields
Electromagnetic Waves
______ is the ability to exert force over a distance or the ability to do work
Energy
The bigger the wave, the more ______ it carries
energy
As waves spread out, successive ____ ______ move farther from the center
wave fronts
Most waves are caused by a _________ ______
vibrating object

Sound waves can be caused by the _____ _____ vibrating
vocal cords
In __________ waves, the particles of the medium also vibrate as the wave passes through
mechanical
The wave front transfers only ______, not matter
energy
A vibration that fades out as energy is transferred from one object to another
damped harmonic motion
Transverse waves have _____________ motion
perpendicular
Longitudinal waves cause particles in the medium to vibrate ________ to the motion of the wave
parallel
_______ _____ occur at the boundary between two mediums
Surface waves
In a surface wave, particles move in _______
circles
similar characteristics between waves
Wave Properties
an ideal transverse wave is in the shape of sideways S
Sine waves
highest point of a transverse wave
Crest
lowest parts of a transverse wave
Trough
the greatest distance particles are displaced from their normal resting place
Amplitude
the time that it takes a complete cycle or wave oscillation to occur
Period
the number of cycles or vibrations per unit of time
Frequency
number of vibrations per second
Hertz
The full range of light at different frequencies and wavelengths is called the _______________ ________
electromagnetic spectrum
The speed of a wave depends upon its ______
medium
the bouncing back of a wave when it hits a surface or boundary that it does not go through
Reflection
a change in the direction of a wave when the wave finds an obstacle or an edge, such as an opening
Diffraction
the bending of a wavefront as the wavefront passes between two substances in which the speed of the wave differs
Refraction
the combination of two or more waves of the same frequency that results in a single wave
Interference
any interference in which waves combine so that the resulting wave is bigger than the original waves.
Constructive interference
any interference in which waves combine so that the resulting wave is smaller than the largest of the original waves
Destructive interference
a wave or vibration that causes the particles in the medium to vibrate in a stationary pattern
Standing Wave
