100
Lowest point of a wave.
Trough
100
a disturbance that carries energy from one place to another.
Wave
100
Amount of energy carried by a wave, which is indicated by the amplitude of a wave.
Intensity
100
highest point of a wave
Crest
100
Property of sound that depends on the wave’s frequency.
Pitch
200
material through which a mechanical wave travels.
Medium
200
distance between two consecutive similar points on a wave.
Wavelength
200
movement that follows the same path over and over again.
Vibration
200
wave that disturbs a medium.
Mechanical Wave
200
Greatest distance from the resting position of a wave.
Amplitude
300
Change in sound or light that occurs whenever there is motion between the source and the observer.
Doppler Effect
300
Bouncing back of a wave upon reaching another surface.
Reflection
300
Wave in which the motion of the medium is at right angles to the direction of the wave
Transverse Wave
300
Bending of waves due to change in speed.
Refraction
300
A form of energy that causes the molecule of a medium to vibrate back and forth.
Sound
400
Number of waves that pass a certain point in a given amount of time
Frequency
400
wave that consists of electric and magnetic fields that does not require a medium.
Electromagnetic Wave
400
Bending of waves around the edge of an obstacle.
Diffraction
400
Wave in which the motion of the medium is parallel to the direction of a wave.
Longitudinal Wave
400
Interaction of a wave that occur at the same place at the same time.
Interference
500
Waves combine in a way that the disturbance results in a greater wave.
Constructive interference
500
Wave that consists of a combination of transverse and longitudinal waves and occurs at the surface between two mediums.
Surface Wave
500
A wave that does not appear to be moving, Occurs at the natural frequency of the material.
Standing wave
500
Waves combine in a way that the disturbance results in a smaller wave.
Destructive interference
500
Frequency where a standing wave occurs.
Resonant frequency
