Define Wave

• A disturbance involving the transfer of energy from place to place

• Gases, liquids, and solids

• The highest point of movement in water

• An area where coils are close together

Define Energy

• The movement of particles from one place to another

• The material through which a wave moves

• The ability to do work

• A repeated up and down, back and forth motion

Define Medium

• The material through which a wave travels

• The ability to do work

• The source of energy that causes movement

• Waves that require an object to travel through

Define Mechanical Wave

• A repeated up and down, back and forth motion

• A wave that vibrates the medium at right angles, and perpendicular, to the direction in which the wave travels

• A wave that knows how to use a wrench

• Waves that require a medium to travel through

Define Vibration

• An area where the coils are spread out

• A shaking of the medium in the same direction in which the wave travels

• Repeated up and down, back and forth motion

• The ability to do work

Define Transverse Wave

• The ability to do work

• A wave that vibrates the medium at right angles, and perpendicular, to the direction in which the wave travels

• Waves that require a medium to travel through

• An area where the coils are close together

Define Crest

• Lancers

• The lowest point on a transverse wave

• The highest point on a transverse wave

• An area where the coils are close together

Define Trough

• The highest point on a transverse wave

• The lowest point on a transverse wave

• The material through which a wave travels

• An area where the coils are spread out

Define Longitudinal Wave

• The ability to do work

• A wave that meets its highest point through length

• A wave that vibrates the medium at right angles to the direction in which the wave travels

• Vibrates the medium in the same direction in which the wave travels

Define Compression

• An area where the coils are close together

• A area where the coils are spread out

• The ability to do work
