100

A unit of measurement for frequency.

What is hertz

100
A disturbance that transfers energy from place to place.

What is wave

100

The interaction between two waves that meet.

What is interference

100

The highest part of a transverse wave.

What is crest

100

The bouncing back of an object or a wave when it hits a surface through which it cannot pass.

What is reflection

200

The interference that occurs when two waves combine to make a wave with an amplitude larger than the amplitude of either of the individual waves.

What is constructive interference

200

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

What is frequency

200

The part of a longitudinal wave where the particles of the medium are close together.

What is compression

200

The bending of waves as they enter a new medium at an angle, caused by a change in speed.

What is refraction

200

The interference that occurs when two waves combine to make a wave with an amplitude smaller than the amplitude of either of the individual waves.

What is destructive interference

300

A wave that moves the medium in a direction parallel to the direction in which the wave travels.

What is longitudinal wave

300

The lowest part of a transverse wave.

What is trough

300

The distance between two corresponding parts of a wave, such as the distance between two crests.

What is wavelength

300

The ability to do work or cause change.

What is energy

300

A repeated back-and-forth or up-and-down motion.

What is vibration

400

A point of maximum amplitude on a standing wave.

What is antinode

400

The bending or spreading of waves as they move around a barrier or pass through an opening.

What is diffraction

400

A point of zero amplitude on a standing wave.

What is node

400
The height of a transverse wave from the center to a crest or trough.

What is amplitude

400

A wave that moves the medium at right angles to the direction in which the wave travels.

What is transverse waves

500

A wave that appears to stand in one place, even though it is two waves interfering as they pass through each other.

What is standing wave

500

A wave that requires a medium through which to travel.

What is mechanical wave

500

The part of a longitudinal wave where the particles of the medium are far apart.

What is rarefaction

500

The material through which a wave travels.

What is medium.

500

The increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency.

What is resonance
