This wave is a vibratory disturbance that occurs at right angles (perpendicular) to the direction of travel of the wave
What is a Transverse wave?
100
This transfers energy from one point to another without a transfer of matter between the points
What is a wave (or pulse)?
100
This is produced when 2 or more waves pass through the same place in the same medium.
What is interference?
100
This is the substance that a wave travels through (ex: air or water)
What is a medium?
100
this is the lowest point of a wave.
What is the trough
200
This wave is a serious of regularly (evenly timed) vibrations in a medium
What is a periodic wave?
200
This occurs when a wave bounces off a barrier.
What is reflection?
200
This occurs when the colliding waves are in phase. Each wave adds to the displacement.
What is constructive interference?
200
This unit is equal to 1/second and is also the unit of frequency
What is the Hertz?
200
This is the height of the wave from the baseline. The larger this gets the louder the sound or brighter the light.
What is the amplitude?
300
In this wave, the vibrations occur parallel to the direction the wave travels
What is a longitudinal wave?
300
This is the bending of a wave that occurs as the wave moves from one medium to another medium with a different density.
What is refraction?
300
The resultant displacement of two waves is sometimes called this.
What is superposition?
300
When on object’s vibrations cause vibrations in another object at the 2nd object’s natural frequency by using a wave with the same frequency.
What is Resonance?
300
The number of vibrations that occur in a unit of time.
What is Frequency?
400
This wave is produced when two waves of the same frequency and amplitude travel in opposite directions in the same medium
What is a standing wave?
400
This is the name for the change in the frequency of a sound when the source is moving relative to the listener
What is the doppler effect?
400
This is greatest when the colliding waves are completely out of phase (or the displacements are in opposite directions)
What is destructive interference
400
The speed of a wave is calculated by this.
What is wavelength times frequency (or wavelength divided by period)?
400
This is the distance between two consecutive points of a periodic wave that are in phase. It is measured from one point to an identical point on the same wave.
What is wavelength?
500
Without a medium to travel through, these waves would not exist
What are mechanical waves?
500
This is the spreading of a wave into the areas behind an obstacle or barrier.
What is diffraction?
500
This is the part of the Standing wave that does not move.
What is a node
500
Points on a periodic wave are said to be this when they are moving in the same direction and have the same displacement.
What is in phase?
500
This is the area of low pressure or where the medium is the most spread out in a longitudinal wave
