What is Frequency
These waves DO NOT require a medium. Examples are: x-rays, radio waves, & microwaves.
What is a Electromagnetic Wave
Waves transfer _____________
What is Energy
This is the substance that a wave moves through
What is a medium
The distance between two consecutive points on a wave is called
What is Wavelength
These are the waves that transfer energy through matter. Examples are sound, water, and tsunami waves.
What are Mechanical Waves
The highest point or peak of a wave is the ______, and the lowest point or valley is the _______.
What are the Crest and the Trough
When waves merge together to form a temporary larger wave, their amplitudes are added together to form a
What is Constructive Interference
In this type of wave, the direction in which the wave travels is perpendicular to the direction of the disturbance
What are Transverse Waves
Waves are created when a ________ creates a______.
What are source and vibration
These are the two properties you need in order to calculate wave speed.
What is wavelength and frequency
Regions in a longitudinal wave where particles are farthest apart are called________, and when they are close together are called _____.
What are Rarefactions and Compressions
This is formed when crests of one wave align with troughs of another wave
What is Destructive Interference
These waves travel in the same direction as the disturbance. They also have compressions and rarefactions.
What are Longitudinal Waves
Waves behave in _________ ways.
What is Predictable

What is meters or m
This happens when a wave moves through a barrier
What is Diffraction
This measures how far the wave rises above or dips below its original position
What is Amplitude
