A
A unit of measurement for frequency.
What is hertz
What is wave
The interaction between two waves that meet.
What is interference
The highest part of a transverse wave.
What is crest
The bouncing back of an object or a wave when it hits a surface through which it cannot pass.
What is reflection
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
The number of complete waves that pass a given point in a certain amount of time.
What is frequency
The part of a longitudinal wave where the particles of the medium are close together.
What is compression
The bending of waves as they enter a new medium at an angle, caused by a change in speed.
What is refraction
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
A wave that moves the medium in a direction parallel to the direction in which the wave travels.
What is longitudinal wave
The lowest part of a transverse wave.
What is trough
The distance between two corresponding parts of a wave, such as the distance between two crests.
What is wavelength
The ability to do work or cause change.
What is energy
A repeated back-and-forth or up-and-down motion.
What is vibration
A point of maximum amplitude on a standing wave.
What is antinode
The bending or spreading of waves as they move around a barrier or pass through an opening.
What is diffraction
A point of zero amplitude on a standing wave.
What is node
What is amplitude
A wave that moves the medium at right angles to the direction in which the wave travels.
What is transverse waves
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
A wave that requires a medium through which to travel.
What is mechanical wave
The part of a longitudinal wave where the particles of the medium are far apart.
What is rarefaction
The material through which a wave travels.
What is medium.
The increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency.
What is resonance
